The LAV-AT used the "hammerhead" TOW launcher turret originally found on the ITV M901, and mounted it slightly offset to the hull's left rear corner. The deck of the rear hull was redesigned to incorporated a hatch that provided the loader some protection as he attended his duties. The vehicle's fuel tank occupied the same position as that on the LAV-M, on the left-hand side of the hull rear, and likewise smoke grenade launchers were mounted on the hull roof. Missile stowage racks were placed on the right side of the passenger compartment opposite the loader.

The LAV-AT underwent upgrades to -A1 and -A2 standard like the LAV-25.

The various versions of the TOW missile are as follows: BGM-71A from 1970 was the basic version with a 5" (13cm) diameter warhead and a 3,000m (1.86mi) range. BGM-71B from 1976 extended the range to 3,750m (2.33mi). BGM-71C ITOW (Improved TOW) from 1981 used an improved 5" (13cm) warhead and a 265mm (10.4") long standoff probe which allowed the shaped charge penetrator to assume a more efficient shape before it struck the target. BGM-71D TOW 2 from 1983 had a 6" (15cm) diameter warhead and a 345mm (13.6") long standoff probe, along with a new motor and digital guidance strengthened against countermeasures. BGM-71E TOW 2A from 1987 introduced a precursor charge in the standoff probe to defeat explosive reactive armor. BGM-71F TOW 2B from 1991 was a top-attack weapon using two explosively-formed projectiles that penetrated the roof of armored vehicles. TOW 2B lacked a standoff probe.
