Giff

It’s easy to spot the giff in a room: a group of 7-foot-tall, hippopotamus-headed humanoids attired in gaudy military uniforms, with gleaming pistols and muskets on display. These spacefaring mercenaries are renowned for their martial training and their love of explosives.
Military Organization. Every aspect of giff society is organized along military lines. From birth until death, every giff has a military rank. It must follow orders from those of superior rank, and it can give orders to those of lower rank. Promotions don’t depend on age but are granted by a superior as a reward for valor. Giff are devoted to their children, even as most of their education is geared toward fighting and war.
Mercenaries Extraordinaire. Giff are in high demand as warriors for hire, but they insist on serving in units composed entirely of giff; a giff hiring itself out individually is unheard of. Giff refuse to fight other giff, and will never agree to a contract unless it stipulates that they can sit out a battle rather than wage war against their kin. A giff prizes the reputation of its unit above its own life. Life is fleeting, but the regiment endures for generations or even centuries.
