The CL64 Launcher system is designed around the L64 missile, a solid-fuel driven, guided-rocket projectile. The requirement for the missile itself and its accompanying launcher being man-portable placed severe constraints on size and weight, making the missile rather on the small size. For the Soldat, this shortcoming was to be overcome with a multi-missile rack launch system attached to one or, theoretically, both of the upper-hull actuator joints. The warhead payload approach was, for the time, an extremely novel one and may go a long way to explain Laufey's interest. The L64 foregoes any attempt to do direct damage to targets by using a minor blast effect to aerosolize a payload of variant Smartfoam^TM. The missile detonator can be set to trigger the resulting cloud in one of two ways: an electrostatic shock effect of considerable utility against electrical and nervous systems alike, or a simple thermal energy blast.

SCL-64 Launcher proved a considerable boon for Support troops, giving them an anti-zeo weapon which also had the flexibility to engage a variety of targets. However, the L64 missile proved extremely problematic to integrate with the Soladat's already heavily-stressed control systems. In the end it was necessary to dispense with the excellent designator system used by the SCL-64 and rely on the missile's internal terminal guidance systems for accuracy, reducing it to a slightly smarter rocket rather than a true missile.

TCL-64 “Fusi” Missile pack does supply the Soldat with an option for a flexible area effect weapon and remains in widespread use. However, it must be noted that when designing weapons for the UnS-65 Stormer, the L64 missile was disregarded in favor of a much simpler combat launcher system in the shape of the TCL-3 “Boomer.” A subtle admission of this reframing of the L-64 as purely a Support weapon can perhaps be seen in its reappearance in simplified form as ammunition for one configuration of the Tbd-1 Auto Sentry Turret Drone.
