Everyone who maining Dokkaebi are masochists. I have been coming to this conclusion for 200+ hours of playing. Why? You have to pay with weapons for good ability. read more about this below.

Primary:
1) Mk14 EBR
Marksman rifle, there is an angular handle, which gives an advantage over other DMR. Also has low recoil. I recommend using it in the absence of alternatives. Without the silencer, the mk14 kills fighters with 1 and 2 hits in the body, 3 armor requires 3 hits. It requires three hits with the Rook 2 and 3 armor plates.
Recommendation: Muzzle brake, angled grip, 3x scope, using laser sight is pointless. Don’t forget: unfortified hacth breaks with 6 shots.

2) BOSG.12.2
A double-barreled shotgun with a very high base damage that getting lower with distance. Excellent weapons at close-medium distances, but requires 100% accuracy, for 2 misses you are likely to be punished. When choosing a bosg, think about what kind of sight to put: a canonical acog, or 1x, which will be useful near.
Recommendation:angled grip (recoil after shot is too strong, so it can be compared with AWP chuck charging. Using vertical grip is pointless), scope (based on your needs), using laser sight is pointless (hip recoil is terrible).

Secondary:
1) C75 Auto
CZ is one of the best machine pistol in terms of characteristics. The only minus is the worst front sight in the game, it closes too much of the view.
It is good in medium-close positions, where the DMR loses in time to kill.
Recommendation: don’t use any attachments.

2) SMG-12
It’s very difficult to master this gun, however, you can shoot with it. Practice 1-2 months of T-hunt will let you to control this obstinate baby. It can be used at medium-short distances, the rate of fire allows you to shoot in the head (similar to the smg-11, but more difficult). A special question is the choice of handles. Anyone will tell you, put a straight line, you saw a crazy recoil, it must also be lower! All right. Paradoxically, the recoil doesn’t increase with angled grip.
Recommendation: use vertical or angled grip, a sight to your taste (I would recommend to use Holograph with stretched aspect ratio, and Reflex with default aspect ratio). Laser: you can put it for more accurate shooting at the entrance to the scope, but opponents will shoot at the laser and the glow near the character.
My build is very specific: angled+laser. Experimentally, I found out that this setup is perfect for me. Yes, in this case, the laser contradicts players’ views. Why? The handle allows us to quickly enter and exit the scope. Our accuracy practically doesn’t fall with laser. A small thing, but important. Try to play this way to have an idea~.
IMHO: Imho: I advise experienced players to try changing the aspect ratio, it is easier to control the recoil of the smg-12 with this ratio.

Short summary: we use Mk 14 for long distances, working outside the building and holding corners and cz 75/smg-12 for short distances.

1) Grenades

Always useful. Example:
•Throw in drone hole

•Throwing with delay for blow up in right place vertically/on same levels

•Help with hard breach

Zoning, for example, when installing a deactivator. Very situational, throw grenades without "retention" in the opponent’s exit points.

2) Smoke grenade

They are useful for installing the deactivator, usually taken by command agreement. They are throwing to complicate the exit from the smoke to the enemy, sometimes to hide themselves.

1) Logic bomb (aka call)

Two times in round, you can upload virus to defender’s phones making it vibrating. To disable vibration defender can stop and turn off his phone it takes 6 seconds or doesn’t do anything vibration will end itself in 12 seconds.

2) Cameras hack
You can hack phone of dead defender gaining the access to all defenders cameras (Including Valkyrie’s and Maestro’s cameras, Mozzie and Echo drones)

When use call?
• Before entering the building, thereby you make the droning effective, the enemy will not remain unnoticed.
• When you don’t need the defenders using cameras. For example, Maestro and Echo, trying to bring down the planting, will be forced to turn off the phone, the chances of placing a deactivator increase significantly.
• Suppression of aggressive play by defenders. Roamer, who betrayed his position, is a dead roamer. The call will make a certain impact during the interrogation of Caveira.

Be careful when hacking a phone! It is not worth rushing to hack the corpse's phone immediately the place of enemy death is a rather dangerous place, which will most likely be checked.

Counter peaks:
• Mute. The defender within the radius of the jammer is protected from ringing. Moreover, if the call has already begun, it is enough to enter the radius of the mutiule for it to stop.
• Vigil. He is invisible under the ability on cameras, including hacked ones.

Combinations
• Iq. When defender try to disable vibration his phone will be highlighted by an outline.

•Jacal, Lion. The more anti-roamers, the worse for roamers.
•Ying, Fuze. Dokka can help Yin to enter the site more easily under candela, while Fuze can distract defenders from the clusters and show their approximate location.

I attribute Dokkebi to the middle role (semi-support / flex),usually she is being played as support for other operatives (supporting from the back, droning, ringing), but it can also be a fragger, if desired or necessary.
Your task for the round: to give ringing calls for teammates and / or for yourself in time, it is desirable to hack the cameras. Help with breaching reinforced walls, if any. Then either cover your comrades or help attack.

Q: What is the advantage of a 4: 3 aspect ratio on a 16: 9 (FullHD) monitor?
A: In siege, when changing, the Player model is wider, easier to hit, cracks and holes are more visible and usable, you have to sacrifice peripheral vision and faster movement of the characters. Usually a high viewing angle is set for such an aspect ratio, in the region of 83-90. In addition to 4: 3, 16:10, 5: 4 are often used (I personally take the standard 16 by 9 ratio).

Q: I want to customize Dokkebi! What good skins are there?
A: All released forms / helmet / weapon skins can be viewed at r6loot.com/. I am using an elite set.

Q: You didnt recommend a laser designator anywhere . Is it so useless?
A: The laser designator reduces the spread from the hip, but in siege almost all gunfights requires aim scope. Shotguns definitely need a laser (you have to shoot from them at close range). Otherwise, a red dot and a glow will betray you. Of course, you may dont look at the enemy intended exit , but slightly to the side, shifting the laser point out of the opponent's field of view, but is it worth it?

Q: I'm interested in operative lore.
A: Lore can be read in the game itself, each operator has a personal file section. Analogue is the ♥♥♥♥♥♥♥♥ site of Ubisoft: ubisoft.com/ru-ru/game/rainbow-six/siege/game-info/operators/dokkaebi. I would recommend you to watch the cinematics / short films / trailers of the operation / operatives, which are pretty well filmed.

P.S. my stats at the time of issue manual

And what is the conclusion? May I recommend Dokki to newbies? Yes, she is an easy-to-learn operative, only weapons are a weak spot.If you are a serious player my fellow reader, maybe give ubisoft a request ;).
I wouldn't mind getting a KIA / Hk416 / AR33 / AK-74M into Dokkebi's arsenal...
Perhaps the sight on the cz75 will correct the situation, or the choice of the attachment for the smg-12?..
Good luck to everyone, train your skills and get epic/legendary alpha-packs!
