Things that factor into your mission rank are, in a rough order of importance:

Faster is better. In a lot of cases you can get away with rushing straight to the objective.

"Repair costs" on the result screen, the less the better. Repair kits and resupply don't factor into this, only the overall amount of damage you sustained does.
This means you usually can't rely on running a heavy tank build and soaking up all the damage up front.

The more the better, though this is less important than completion time. Note that the actual "rank points" you get from defeating an enemy sometimes differ wildly from how much they're worth in credit payout.
Overall, taking out whatever you encounter on the way to the objective while not going out of your way to sweep everything in sight is a valid strategy.

"Ammo costs" in the result screen. This one seems to be really lax, unless you deliberately go overboard.

Additional info:

• Restarting from a checkpoint caps your rank at A - don't do it.
  
  
• Some missions have their unique requirements for an S-rank, these will be mentioned if present.
  
  
• Missions with boss fights tend to have relaxed time and damage requirements, with the only real challenge being beating the boss itself without restarting from a checkpoint. Just completing the entire mission in one go within a reasonable time is usually good enough for an S-rank.
  
  
• For missions with bonus pay or penalties, on the results screen there's a "Show details" option, which gives you a breakdown of where those bonuses and penalties came from. Good to know, but in many missions the bonus pay doesn't actually impact your ranking.
  
  
• For each mission below I will specify the assembly I used and the result I got on the end screen, as well as time spent - for reference.

Note that the guide was written for patch 1.01, but as of patch 1.04 despite the weapon rebalance the strategies provided below are still very much valid.

For this one you're locked into your default AC, Loader 4.
You can either assault boost through the entire level, only destroying enemies around the wrecks, or move slightly slower and destroy everything you encounter, both seems to be valid for an S-rank. The quickest path through the three wrecks seems to be from left to right.

Before the chopper boss appears, climb on top of a nearby silo on the left to get a running start. Stick close to the chopper as much as you can to prevent it from using its missile attack and just spam everything you have at it. If it happens to fly out of bounds, hide behind the silos to avoid the missiles - just jumping or QBing seems to not be enough to escape the blast zone.

Without hunting down every enemy on the map, just rushing the objectives while destroying whatever you encounter along the way is enough. Plasma missiles worked well for me since only one is enough to destroy any target you encounter here.

Alternatively, a full sweep without taking too much time also works.

Special requirement: Accept RLF's deal and defeat the Redguns

In the first half, all enemies around the generators have to be destroyed, same as the regular mission.

In the second half, you're against Volta and Iguazu - a tanky and a lightweight AC at the same time.
There's a trick to making this significantly easier: attack Iguazu to aggro him, then retreat towards the dam where an RLF tetrapod MT is stationed (vector 250 from the second generator). This will turn the encounter into a 2v2, giving you a lot of headroom. Single out Iguazu first, as he has less health.

Damage and time requirements aren't particularly strict. I recommend a medium or heavy assembly to avoid getting overwhelmed by Volta's heavy weaponry.

Reference assembly:

Reference results:

It's possible to skip most if not all enemies on the way to the Strider.
To avoid Strider's long range laser, you need to be airborne and QB to the side in time. You can afford get hit once or twice, as long as the rest of the mission goes smoothly.

Once on the Strider, you can use explosive weapons of your choice to damage sub-generators from any angle, without having to aim for the exposed rotor. When the eye becomes vulnerable, rush it down with close-range weaponry and melee.

I recommend either reverse-joint legs for more jumping power or tetrapod legs for hovering around the structure.

Reference assembly:

Reference results:

This otherwise daunting mission can be trivialized if you use a tetrapod missile platform type assembly and just hover at a comfortable altitude of about 200, raining guided explosives at the targets below. Use the downtime between waves to land and recharge.

Regular-type missile launchers work great, but vertical, split or cluster launchers will have trouble hitting targets with how fast they are. For even better results, bring Pulse Armor and a FCS with good missile lock-on time.

Repair cost wise, with this setup you should be fine as long as you've within two repair kits worth of damage.

Reference results:

With sufficient speed you can safely ignore all non-target enemies outside the wall, only attacking those inside. At the start of the mission, keep an eye on the Juggernaut in the distance as it will bombard you with artillery from afar until you're about halfway through the city block.

I find it easiest to assault boost towards the moat, then fly or catapult yourself up on top of the rampart and attack the gatling guns from above. After that, rush towards the BAWS tetrapod and get behind it to stay out of range of wall-mounted artillery. From there on, it's straightforward.

The Juggernaut is vulnerable not only from behind, but also from above, so an easy strategy is to jump above and over it while spamming close range weaponry and/or explosives, following up with melee when it's exposed for a direct hit.

I find reverse-joint builds to be most comfortable here, both for navigating and for combating the boss.

Reference assembly:

Reference results:

Special requirement: Find and collect all eight logs

• two logs are in the starting area, in front and to the right of the starting point
  
• one log is at the foot of the concrete wall off the far left corner of the starting area, under the enormous fallen pillar
  
• two logs are in the ravine at the base of the fallen pillar
  
• three logs are scattered around the snowy path coming out of the starting area and tracing the edge of the ravine

You don't need to engage any enemies including Ziyi, but at least clearing out those around the wrecks helps with reducing damage sustained. Upgrading scan speed in your OS is a big help, obviously.

I recommend bringing an agile build with multi-lock weaponry to quickly clear out minor enemies without taking your attention off the main objectives. You can also bring a pulse shield to put up while scanning if you want to be extra safe.

Reference assembly:

Reference results:

Special requirement: No more than 25% damage dealt to the helicopter

This one is difficult. The only consistent method I've found is to memorize the helicopter's route and rush ahead, destroying every enemy you encounter way before the helicopter even gets there.

The only enemies that spawn in along the way are the three quadcopters carrying MTs, they appear as your helicopter leaves the first landing point. All other enemies are already on the map, though some of them are hidden out of sight - I recommend using a head unit with good scan range to look for those.
Note that you don't have to destroy the combat log tetrapod MT.

On top of all that, at the end you'll also fight G2 Nile, a heavy biped AC, all the while transport choppers constantly bring MT reinforcements. I ended up having the most luck with a reverse-joint assembly with twin Zimmermans and a melee weapon (for the G2 fight) as well as a multi-lock launcher (for clearing the path beforehand).

To make the fight with G2 Nile easier on your escort target, you can also bring either Pulse Protection - to raise the protective dome around the helicopter while you deal with G2, or Assault Armor - with good timing you can activate it to get rid of all four MT-carrying quadcopters that appear alongside G2.

All ghost units aside from the last four in the well are actually present on the map at all times, meaning you can get a drop on them if you know where they are.

I recommend bringing a head unit with good scanning range and first proceeding through the map carefully, scanning ahead of you to find the ghost units:

• one in the first section, firing at you - you can't get a drop on this one
  
• three in the next section: on the right behind boxy machinery, on the left behind a structure with a U-shaped top, and towards the back-left on a concrete ledge
  
• three in the last section: to the left on a stack of curved plates, to the left behind reddish angular machinery and to the right between crane arms

Once you know where they hide, one Songbirds hit on an unaware ghost unit is enough to destroy it.

This also holds for the fight at the bottom of the well - use a long range scanner to find the three units latching to walls (one on the far wall towards the left, one on the left wall towards the back, one on the right wall towards the back) and you can shoot each of them down with a single Songbirds volley, leaving only one non-cloaked unit to deal with.

Straightforward and not as scary as it looks. During the boss fight, I find it easier to first go for PG (the one on the left, as Kate tends to focus on the one on the right), then the MG, and leave Cataphract for last.

Damage thresholds aren't strict, with good completion time you can get away with eating all three repair kits.

I used a reverse jointed twin Zimmermans & pile bunker assembly for this. Alternatively, a twin gatling & twin stun needle assembly on Fortaleza light tank legs is a comfortable choice.

After dealing with Rummy, you can ignore everything else and rush straight to the boss gate. Note the explosive containers hanging on the ceiling in front of the gate - you can shoot these down to destroy all MTs below and damage the tetrapod as well.

For the boss, a reverse-jointed or tetrapod assembly will allow you to hover above its sweeping attacks, while putting you in a position to fire at its chimney weakpoint.

The mission is short and not difficult, but time and damage limits are strict.

In the first area, right at the start you can fly up and use long-range weaponry to dispose of enemies on the platform above, that way you won't need to wait for them to come down later on.

In the second area, taking out the groups in the order of left → back → right seems to be the most comfortable path. Make sure to have enough energy before you start assault boosting over the gap.

I recommend multi-lock weapons to tear through the MTs and a lightweight assembly to dodge the large homing missiles they fire at you in the second half.

Reference assembly:

Reference results:

Special requirement: destroy the combat log heavy tetrapod MT

You get credit penalties according to the progress of the hack, but it doesn't actually affect your rank.

The quickest path through the hacking drones seems to be:

• the drone just in front of the entrance, on a lower level
  
• open the door behind the drone, and in the next room drop to the level below for the next one
  
• fly up to the walkway above the previous drone and open the door on the left, then the next one in the corridor - the drone is in this room
  
• from there, make a U-turn (vector 120 from the previous drone) and follow the tracks to the intersection where a tetrapod appears, turn left from there
  
• the last one is in the room to the right of said intersection

Note that defeating Iguazu too quickly will leave you alone against five ghost machines - you may want to pace yourself.

Since both Iguazu and the ghost machines use pulse shielding, and there are a lot of clustered targets in the first half, bringing Assault Armor is recommended. A pulse gun and/or wide area of effect explosives are viable choices. A head unit with good scanning range helps with locating the drones if you're lost.

Reference assembly:

Reference results:

The jellyfish-like drones don't factor into your score at all, so it's safe to ignore them along the way. To shave even more time off your total, you can use Assault Armor to instantly dispose of those hovering over the boss arena.

A tetrapod assembly will allow you to comfortably cross the gap between platforms while hiding under the bridge, as well as follow the spider up into the air in its second phase. As long as you stick close to the spider, you should be able to outdamage it easily enough.

Reference assembly:

Reference results:

The first half is straightforward, rushing the objectives and taking out whatever is in the way should work fine, with multi-lock weapons being a big help.

In the second half, I don't recommend rushing the tetrapod, as the smaller MTs tend to get in the way, even though they get destroyed by the warship soon after.

To make the fight against LCs significantly easier, use the catapult to get on top of the cliff and fire an explosive of your choice into the warship's bay as it opens - you'll deal major damage to the LCs before they can even do anything to you.

Afterwards, as the warship makes its second pass, fly onto its deck and take out the bridge. Note that the various cannons on its body as well as the drones it launches don't count towards your score directly, though taking them out helps mitigate damage.

The biggest factor against the S-rank seems to be how much damage you take - if has to be under about two repair kits.

Reference assembly:

Reference results:

Special requirement: Destroy the combat log LC in front of the bridge
While the shield LC in front of the bridge is the only mandatory requirement, destroying only this one and nothing else means you will also need to keep time and damage to an absolute minimum for an S-rank.

With repeated attempts I've found that destroying the other two combat log LCs as well makes getting the S-rank much more consistent, so I do recommend destroying all three:

• a shield LC right in front of the bridge
  
• a sniper LC on a tall structure in the distance, to the right of the bridge
  
• a sniper LC underneath the bridge, near the catapults

I was getting the best results with those three destroyed, as well as using plasma missiles to take out whatever smaller enemies were along the way as I moved through the map, without leaving the fastest route to go after anything else.
Note that destroying fuel tanks actually doesn't factor into the ranking at all.

Both the shield LC and Ekdromoi units are vulnerable to an assault boost kick → twin shotgun blast → charged pile bunker combo.
When fighting the two Ekdromoi, focus the melee unit first, as otherwise it will disrupt you with its long range lunges. A close-range FCS is recommended.
A good strategy against the Ekdromoi is to immediately move left at the start of the battle and lure them into a corner of the map, behind a storage tank, where their mobility will be limited and they'll be vulnerable to melee.

For the results below, I was moving through the map at a speedy but not breakneck pace, and apart from the three LCs I only destroyed those enemies that were directly along the path, mainly using plasma missiles. I also took quite a beating during the boss fight.

You don't need to fight Rokumonsen or any of the combat log enemies.

I find it easiest to hug the left edge of the area and proceed on top of the walls, using long-range weaponry to get rid of MTs along the path. After reaching the objective, turn around and make a beeline to Swinburne. The damage threshold is about two repair kits.

Going for the HC (the left one) first is preferable, as it takes some time to activate and react to your presence. Other than than, pretty straightforward.

Time and damage are the main factors, and most enemies along the way can be ignored. Self-destructing ball drones don't even factor into your score at all.

A well-timed burst of Assault Armor can stop the ghost units' ambush in its tracks and immediately open them up for a direct hit.

During the bossfight, I find it's worth taking the extra time to activate the friendly drones, as they make the battle much less hectic.

I found a medium weight, reverse joint twin shotgun twin stun needle assembly to be the most efficient against the helicopter. Alternatively, a hovering tetrapod with close range weaponry also works.
A long-range missile assembly might seem like a good idea but in actuality it tends to be too slow and ammo hungry to reach an S rank.

The alternative mission replaces the helicopter and sniper LCs fight with a single heavy biped AC, Astghik, making the mission arguably easier.

Bring an anti-AC assembly of your choice, and don't stand in napalm for too long.

Special requirement: All three missiles survive
Individual missiles can be heavily damaged, but once one is destroyed, the S-rank is lost.

The main problem are the three toybox mechs that arrive at 02:20, and the warship that arrives at 01:15.
Toybox mechs fire rocket salvos that can shave off half a sub missile health, and if the warship is allowed to fire off its laser sweep, the S-rank is as good as lost.

Keep an eye on the radar and use an agile assembly with a mix of long and medium range weapons. I recommend plasma missile launchers for their range, lock speed and overall good performance against clustered targets.

Special requirement: No transport choppers escape the area

While you don't need to destroy every non-target enemy, it's still recommended to do so as not destroying enough enemies while sustaining a large amount of damage may lead to an A-rank even if you managed to shoot down every chopper.

Note that the choppers explode in large AoE blasts. You can't really set off chain reactions, but there are instances where blowing up one chopper also destroys one or two choppers next to it.

Pay extra attention to the very last wave with the choppers coming en masse both below and above. At least one chopper usually tends to slip through the head-on assault, so keep an eye on the TGT indicators to make sure no stragglers have made it past you. If they do, chasing them down should pose no problems, as long as you notice them immediately.

After running this mission multiple times, I've found the most comfortable and consistent assembly to be a hovering tetrapod missile platform, with the specifics provided below.

Using multi-lock for the plasma launchers works great for clustered targets, choppers or otherwise, while the split missile launchers provide enough accuracy and damage to reliably one-shot from maximum range everything but LCs.
Note that the most efficient way to use Coral generators is by letting them bottom out and recharge from zero. If you don't vibe with this kind of playstyle, switch to a traditional generator.

Keep an eye on the compass as it shows the worm's location even when it's underground.

From the start of the mission, keep moving forward-left (vector 220) and you'll find yourself in the perfect position to strike.

I recommend bringing twin stun needles in case you miss the initial shot. This also gives you an opportunity to break the worm's shielding in the third phase with just a single volley. When the worm is down, a pile bunker and a close-range weapon of your choice should take care of it no problem.

At the start of the second phase, you can try switching to manual aim sniping the worm from afar, as it moves in a straight line towards you.

I also find it useful to bring reverse joint legs and boosters with good vertical thrust, so that during the worm's big discharge attack in the third phase you can maneuver yourself to hit its face.

Reference assembly:

A mission where you can go full tank. Bring a heavy and stable assembly, equip Pulse Armor and the heaviest pulse shield.

From the start, instead of activating the elevator, just jump off the platform.

The only obstacle is a small squad of MTs halfway through the shaft.

After defeating Iguazu, you can rush through the rest of the level ignoring everything including the PCA ambush. If you decide to get rid of the PCA machines, you can do so while they're still dormant, before you hack the terminal.

Damage thresholds aren't strict, you can eat through three repair kits and still come out with an S-rank.

Different from the original in that Iguazu is replaced with Coldcall, who is much more agile and aggressive.

Time requirements are somewhat tight, but damage requirements are generous - you can finish without repair kits and with health in the red and still get the S-rank.

I recommend bringing a plasma missile launcher, it's a massive help for cleaning out MTs and quadcopters quickly. For this mission, I even find it easier to bring two of them and forgo a melee weapon.
Make sure to use multi-lock and try to pop the quadcopters before they fly away - these count towards your score.

Against Michigan, I find it easier to sweep the MT in the vicinity first and only then focus on him proper.

Reference results:

Time and damage thresholds aren't strict at all, so as long as you beat the mission in one go, chances are you'll get an S-rank then and there. The difficulty comes from the boss being a glass cannon who's capable of melting you if you're not careful or just unlucky.

You don't need to fight anything in-between the starting skirmish and the boss, so just rush through the level.

The Ibis unit will always open the fight with the same big sweeping attack that leaves it standing still for a moment, perfect for a counter. For the second phase, it becomes vulnerable right as Ayre finishes saying "environment", so time your opening attack accordingly.

A direct pile bunker hit will shave off half the Ibis unit's health bar, but it's tricky to connect with, so you might want to opt for something faster or with better range, or even drop melee altogether for stun needles.

If all else fails, a Fortaleza tank legs twin gatling twin stun needle assembly will make use of the flat boss arena and carry you through the fight with relative ease.

Special requirement: Xylem shield isn't breached and Xylem tower takes no direct damage

The main problem are snipers that appear at 03:00 and kamikaze drones that appear at 01:50. Other enemies can be easily dealt with using a plasma missile launcher for clustered targets and a laser rifle for stragglers. Particularly, VE-66LRA (the medium laser rifle) can one-shot every minor enemy.

Defense cannons are surprisingly useless, but you can activate them at around 03:15 to get rid of three or four snipers. For the rest, I find it easiest to hang out in the center area and use explosives and/or plasma missile launchers to one-shot them from long range.

Kamikaze drones are the dealbreaker here as they will eat up more than half the shield if left unattended. Fortunately, there is an easy and consistent counterplay: stand on the ledge in front of the main tower, and as the drone indicators appear, fly up to an altitude of about 260 and place the Pulse Protection core expansion there - it will neutralize every single drone.

The next wave includes a heavy PCA craft approaching from the center path. You don't need to destroy it, but you should at least aggro it to take its attention off the tower.
