I now throw my hat into the ring. Many thanks to both Hayden for the helpful hints and CakeBandit's video on YouTube. Is this a great community, or what?
This Hunchback is painted in the battle colours of the Harmless Little Beavers, a Mercenary Unit formed within the borders of, and employed by, the Free Rasalhague Republic. The paint scheme is a loose representation of the Canadian flag, a nation state on the planet Terra. The unit logo is located on the left thigh and depicts a portion of the Canadian flag, the industrious Beaver [as ferocious looking as possible], and the logo of the FRR. The logo of their current employers is found on the right leg of each Mech.
The unit was formed on the planet Trondheim, a planet that saw many Canadian settlers in the early years of colonization. Indeed, many of the founding officers can trace back their heritage to the North American country, and the unit colours and logo are a nod of respect to their ancestors. Something of note regarding the unit logo. It seems that a very old comedy troupe called 'Monty Python's Flying Circus' made a movie, 'Monty Python and the Holy Grail'. This film was a farcical journey filmed in the 1970s, it is believed. At any rate, a scene from the movie had a nasty little rodent of some kind killing off Medieval knights. Armed with vicious teeth and the gift of flight, this rodent made short work of these knights by biting their necks until the hapless victim was decapitated. Silly, to be sure, but the idea of the tiny creature besting armoured men struck the funny bone of the unit commander, and thus the motif and company motto… a line from the movie. Mistakenly thinking the small rodent was the Canadian national symbol, the Beaver, it was adopted as part of the unit insignia, fitting for a unit tracing roots and inspiration from that sovereign nation. It was only after the MRBC had registered the unit name and logo that the mistake came to light… the rodent in the film was actually a fluffy white bunny rabbit. Satisfied that very few people, if any, would recognize the error, the unit decided unanimously to stick with the name, logo and colour scheme.
