Sentinel

A new, upstanding and official name for self-proclaimed proud campers in Call of Duty. 'Sentinels' differ from regular ol' nooby campers who do it because they don't really know how to play the game; sentinels purposely camp because they are trying to play the game "tactically" and "realistically", even though Call of Duty is an arcade shooter. Sentinels are almost always highly casual console players (mostly military nerds) who have no interest in playing the game competitively; they are the type of player that is more suited to playing Arma or Insurgency, but instead plays Call of Duty, since they don't own a PC for Arma, and don't know about Insurgency, since it's simply an obscure indie game in the face of Call of Duty's massive marketing and influence, especially in the console market.
