tsg officers are not routinely armed, but are equipped with speedcuffs, monadnock fixed batons and cs/pava incapacitant spray like divisional officers. tsg does, however, have its own firearms capability with some officers being trained as authorised firearms officers (afos) on standard-issue firearms such as the glock 17 and heckler & koch mp5 semi-automatic carbine, as well as less-lethal weaponry such as the l104a1 baton gun and x26 taser. officers conduct certain infrequent armed patrols within london, usually supplementing specialist firearms command. instead of tsg officers wearing standard black trousers and white shirt, when policing demonstrations they often wear fire-retardant overalls with their stab vests underneath.
