suggestions & reasons why:
You may recall James Degenhardt aka RPGsheets aka Amalor Myrnnyx, a well-known painter extraordinaire, who passed away 3 years ago. (March 2014) He had created several homebrew mercenary units, but only one fits.
AUTUMN'S HARVESTERS I can't recall much beyond it being a mixed force of battalion-ish size.
A second offering would be in honor of Chris Dickerson AKA DREAD, who passed away in November 2015.
DREAD'S NAUGHTS. I think he said it was about regiment in size.
final suggestion: RONIN'S REGULATORS. A cavalry battalion with a mix of fast mediums and hovertanks.
