Various varieties of man-portable missile weapons have incorporated subspace induction rings to launch projectiles. A shoulder-mounted tube is encircled by a paccel ring. The soldier rests the tube on his shoulder and looks through a viewfinder mounted on the inner edge of the ring. When the trigger is pulled the missile in the chamber is sent about 3m (10 ft) forward, at which point its rockets engage and it continues on its trajectory. The subspace jump the missile takes is extremely precise to ensure accuracy. The jump takes a minuscule amount of time, but that time is highly variable. Fortunately, a difference in responsiveness between .0001 seconds and .000000001 seconds is massive in mathematical terms but negligible in real life. Users occasionally report a delay in firing of up to one second, but it is extremely rare.
The most common variety is the Karl Gustav MkVI.
