text: what's the difference between an army ranger and a green beret? my friend is a green beret.  i called him a ranger and he appeared offended. many green  berets are also qualified rangers. green berets are trained in unconventional (guerilla) warfare, but are mostly tasked with indigenous force multiplication. they train irregular guerillas to in the arts of soldiering. a ranger, could be referred to as a "super tropper" they're trained in patrol, ambush, assault, etc. over any terrain, in any weather, against any type of target. in addition to the "ninja" type methods of recon, or ambush. both are elite soldiers, but have very different missions. green berets actual name is "special forces". but this term has been popularized by the media to refer to any type of speciall operations soldier.
