The LAAS-12 was relatively small, man-portable missile tube that was folded when in storage or not in use. The user was required to slide a collapsable tube fromt he rear of the weapon to prepare it for use. The launcher had a low-profile scope on the top of the weapon, which could wirelessly connect to a helmet HUD and use an invisible laser to paint targets prior to firing. A series of simple buttons on the side controlled the safety and engaged or disengaged the heat-seeking capability of the missile. Finally, a large, square button on the underside of the selector unit fired the weapon if the safety was off.
