Her Majesty's Royal Loyal Musketeers ("The Mavericks") is a fictional Irish Regiment of the British Army mentioned in Rudyard Kipling's novel "Kim" and the novella "The Mutiny of the Mavericks".
The nickname is from the Bull in their colors. Mavericks are stubborn, unbranded cattle that are hard to keep in the herd, much like the independent-minded troops of the regiment. They seem to be a tough regiment with a fierce reputation because in "Kim" they are respectfully known by the natives as the "Red Bullock Men".
Cap Badge: A crowned gold Irish Harp.
Regimental Badge: A red Bull furieux [A Heraldry term that combines the terms Salient (depicted rearing upon its hind legs and striking with its hooves) and Enragé ("maddened" - depicted red-eyed, nostrils flared, and baring its teeth)].
Regimental Colours: A white field with the Cap Badge set in the center on a blue rounded and the red Bulls set in the corners.
Battle Honours (Mentioned in "The Mutiny of the Mavericks"): Vittoria (sic), Salamanca, Toulouse, Waterloo, Moodkee (sic), Ferozshah (sic), Sobraon, Inkerman, The Alma, and Sebastopol (sic).
The battle honours should be listed by date, but some of the battles are out of order. There is also some mention of the Indian Mutiny of 1857 and the wars in Afghanistan in passing, but it is unclear wheter they are Honours or just campaigns the regiment served in.
