First i'll explain what POWs are.Pows are war veterans that were captured by the enemy,and if freed,other units and Base upgrades will be avaiable for you.But you must free ALL of them,whose numbers depends of the level itself and the number requirements for freeing a character.The remaining number of POWs to free will be shown on the POW screen on the Map Menu.Normaly,you'll need to free 3 POWs on each stage of the areas,and this number will increace as you continue.

Not all of them are free,so it is your mission to get these good soldiers back to safety.The first unit you'll ever get and the one that will be the most useful in the subject of rescuing POWs will be the plain Soldiers.Yes,the puny grenadiers you have as you start.These guys tosses theyr grenades hing enougth to find POWs hidden on stages.The tactic of the Rescue Team,as i call it,is of upgrading your AP first,then use it to make a group of soldiers (Three soldiers to five of them).When your first soldier prepares his Super Power (Shown as a blue "flame" on the unit),be quick enougth to make him use it right after he leaves your base,to make sure you wont miss a POW hidden bellow your nose.Once the number of soldiers reaches 3 or 5 or when theyr Super Power is activated (Not depending of the number,thought),keep clicking so they use theyr grenades not just to kill/damage enemy units,but to earn collectibles,AND mostly important,hidden POWs.Another thing to be right to say is that it is theorized that as units advances,POWs hidden in the area that they already went wont be able to be freed.It is why you MUST place your soldiers first to prevent quickier units to advance and make you loose your precious POW.But this has some chance to happen.One time or another,you might be able to rescue a fellow prisoner behind your army.

So the enemy came up with tanks and bazookas?Soldiers aren't strong enougth to keep attacking after two blows from the Bazooka Soldier,much less after one from a normal tank.If your soldiers vanished into dust and oblivion,then invest your AP on stronger units that can also attack indirectly,such as throwing projectiles into the air hing enougth as the Soldier.For instance,Fio's Rocket Launcher is good enought as the blast radius is bigger than Soldier's grenades,giving more chances to find POWs.But this will only happen if the rocket does not blow first because of a blocking enemy unit.Other units,such as Ostrich Slug or SV-Camel (both with Eri and Fio,in sequence,wich does not matter.The only difference is that the Ostrich is faster but can throw only one grenade per Super Power,while the Camel can throw three in a row but is relatively slower than the Ostrich).Theyr Super Power,to build up,is slower compared with the Soldier's,but they are stronger and more powerful against tanks and stronger soldiers/enemies,and to find POWs too.

Radars can be bought and awarded depending of what you should do.Getting online each day might reward you one or a few if it is on the reward boxes,or MAYBE if you complete all the stages of a world,and some stagesrewards the player with one or two if he/she completes it.The Radars make sure that you'll find ONE POW upon WINNING the stage.They can be used by clicking on it's image when selecting the stage.Make sure you get this one!
