The mechanism of the PIAT was mind numbingly simple. The Spigot was propelled forward by a huge spring. This spring was compressed by unlatching the shoulder pad, standing on it and lifting the body until the spring and the spigot were almost completely withdrawn and then returning the body to the shoulder pad and the weapon was ready to fire. A bomb was placed in the tray at the front so that when the trigger was pulled the spigot was released entering the tail unit of the bomb thus detonating the charge. This explosion blew the bomb off the spigot and forced the spigot back into the body thus re-cocking the weapon ready to be re-loaded.

Fascinerande pryl, min tekniska engelska är inte så bra - om jag fattar rätt så:
1) Man spänner jättefjädern Hubert manuellt
2) Man lägger på granaten
3) Man avfyrar, fjädern slår fram mot granaten
4) Någon form av mindre drivladdning exploderar
5) Kraften från fjädern och drivladdningen får iväg granaten
6) Kraften från drivladdningen spänner fjädrn igen
Har jag begripit det hela korrekt?
