The Gun of Command was a high-tech weapon manufactured by the Royal Armaments Guild of Charubah.
The gun was more dangerous than almost any other weapon because it made victims unable to distinguish between their own thoughts and the enemy's, allowing the Hapans to control them. The guns worked by releasing an electromagnetic wave field which disabled the victim's thought processes. Once affected, the victim would follow any simple command given, even blatantly suicidal ones. In fact, the Gun of Command was used as a form of execution, where the condemned male (no females were executed on Hapes under any circumstances) would be shot with the weapon, then handed a blaster and ordered to take his own life.
