If you can go online on your PSP, the you can get the EU camo soldiers. The easiest way to obtain them is to create a new game, a capture mission on real combat mode (RC). Make it so only one other player can join. Set the kerotan keep time to 5 seconds. OK. When the game starts, make your way to the kerotan and keep it for the 5 seconds. You will win and you will get new recruits for winning. You only get the camo soldiers if you are lucky.
I have obtained the following camo soldiers Denmark Camo French Camo UK camo Italian camo German Camo Finland Camo A Blck Camo Soldier Spanish Camo
