USAF Advanced Designated Marksmen often provide base counter-sniper security. Armed with M24s or M107s and operating in 2-man teams, they are far closer to traditional snipers than infantry designated marksmen who are sharpshooters in a rifle squad and usually carry semi-auto accurized M14s or M16-based rifles.
