The Clan Fire Mandrill standard always appears on military machines, though not always prominently displayed.

The Kindraa standard is a sword piercing an anvil, set inside a red field with a black border. For every kill a warrior makes, a sword is painted on the right arm or wing of his machine (or battlesuit). Red swords denote 'Mech kills, black swords fightercraft and small red daggers denote Elementals.
