Been working on these guys for far too long so I finally sat down and finished them. They are the Kraków Winged Hussars, a unit of highly-trained Polish mercenaries, and like their namesakes, they are all-out, take-no-prisoners warfighters with a reputation for martial excellence throughout both Earth and the Near Colonies.
This is the basic combined-arms maneuver element of the Hussars, which they refer to as an "Eskadra." It consists of an expanded Mechanized Infantry platoon, an Armored Platoon, support and command elements (an AAA missile vehicle and an 84mm RAP mortar carrier), and, in this case, a pair of armed ISSCV Downships for close air support and EVAC in case of emergency - each Downship can carry half the infantry platoon, or a single tank or APC (with or without its squad mounted).
The Hussars are veterans of campaigns in Ukraine, the Russian Confederation, Sulaco and Costaguana, Mexico, Cuba, and North Africa during the First Upheaval. They were also instrumental in the defense of Tycho on the Moon during the Cresinon War, and have locked blades with the Regimento Acero on more than one occasion, most especially on Io and Ganymede during the now-infamous Battle of the Argentine Moons.
I'm already planning some expansion for the basic force here - an airmobile platoon, a medevac element, and a superheavy dropship to carry the whole unit around.
