Militech Hotshot L-ATGM

Militech Hotshot L-ATGM is a wire-guided light anti-tank missile. The launcher is a tube that boosts the missile onto the battlefield with a recoilless rifle-style blast of compressed air, to avoid tell-tale heat signature. The Hotshot is typically thermograph-equipped, but can be made laser-guided or even outfitted with simple optical guidance. Each missile costs 1500eb.
