What is a light anti-tank rifleman (LAT)?
Fireteams will typically carry light anti-tank weaponry if enemy armor is expected to be present in an area. Generally, this will result in the team's rifleman being given a single-shot light anti-tank weapon like the AT-4 or M136. The anti-tank rifleman will carry out their normal rifleman duties, and in the event that enemy armor is encountered, they will immediately transition into anti-tank mode and attempt to take it out based upon their team and squad leader's directives.
As their name implies, light anti-tank launchers are an effective weapon for usage against light armor such as armored personnel carriers, while heavier armor such as that found on main battle tanks will require multiple impacts from LAT weaponry to defeat.
