How to save a life
During a battle it's likely you'll find an injured soldier, when approching him a pop-up will appear requiring you to use one of the three medical items (syringe, scrissors, medical forceps) Using the wrong item will only make you lose time, using the correct item will save that soldiers life. (Notice: Depending on which soldier you save there are two posible outcomes: If the soldier you save was on your team he will thank you and return back to the battlefield, if the soldier you save was on the enemy team he will thank you and surrender.)
