PLX-1
this was the first version of the Merr-Sonn Munitions portable missile launcher, first introduced during the Clone Wars for use by the clone troopers of the Army of the Republic. Like its descendants, the PLX-1 could fire "dumb" missiles that had to be aimed by the trooper, or "smart" missiles that could locate their target based on heat signature or gravity-activated moed (GAM) missiles. The PLX-1 could hold two projectiles, one in the barrel and a second in reserve.
