Here's a heaping helping of ORRA units! I estimate that by the late 1940s, there are likely around 30-40 ORRA Units (unofficially called Brigades), with around 3,000-10,000 men a unit, with most closer to 3,000 than 10,000. Elite shock troops, death squads, Torchboys, spearhead assault specialists, guardians of the public fluids, and the first glimmer of special forces. Also, proven to be descended from original colonists or puritans, in the peak of health. Also, absolute right dicks.
EDIT: If we average ORRA units as having 5,000 men, and we say there are 40 units, that puts us at about 200,000 troops. Now, we'll say that's the active duty. There are still paper-pushers and units not going to the front. Plus there are some units that are far more than 5,000. I estimate there are about 300,000 ORRA "employees" in the late 1940s. For contrast, there were 800,000 SS in 1944. I want ORRA to keep their "punch" and not seem like they are the only ones fighting in South America. The GAR is doing the most of the slog by far. Basically, I want to avoid the Star Wars Stormtrooper effect, where elite troops become canon fodder and you forget they aren't just the army itself.
For anyone who would like to make their own, hilariously the font I used is called "Evil Empire."
