While this is lumping a few separate jobs together, troops such as Navy SEALs, Army green berets, Air Force combat controllers, and others conduct particularly risky missions. They train allied forces, hunt enemy leaders, and go on direct action missions against the worst of America’s adversaries. They get additional training and better equipment than other units, but the challenging nature of their mission results in a lot of casualties.
