Okay, I'll clarify-
CTRG goes by callsigns for individual operators, to keep both a clear cut comms as well as you know, some degree of identification. Thing is, it's an unofficial structure within "Hoplite" that Arran has taken command over- and Alpha Squad is headed up by Alpha-Actual, or Zdislav, while Bravo Squad is headed up by say Linn, who would become both Praetorian and confusingly enough, Bravo Actual. Or Bravo-1, using sub-fireteams such as Red, Blue, White and Gold if required.
Basically, the way it's devised is such within Tempest, in terms of organizational structure:
HQ Element- Huscarl acts as Platoon Leader, or the impromptu one. And soon to be Leader of the remnant forces left on Stratis, due to his rank- he'd take overall command of the situation, but still remain on direct line to the squads below. Support units are attached- such as radio units, fire support and so forth.
Alpha Squad- Best of the best thrown into Mischief's command, working as a northern (ie. Nisi Bay, Old Outpost area- anything north of Camp Tempest) as initially a recon squad, but they'll become the all-out assault team. They're the hammer blow really.
Bravo Squad- The rest of Hoplite Platoon's best,. under Praetorian's command, working towards the east of Camp Tempest, as again, a recon force, soon to also follow up as an assault team that backs up Alpha when required and usually acts as the secondary force. Linn here would be say, Bravo Actual, with Fireteams within perhaps divided as Blue and Red, or colors of your choice- I know that NATO phonetics work better for fireteams, but in this circumstance, but I'm sticking to that with squads on the whole and colors on the fireteams.
Charlie Squad- Walking wounded along with the rest of Hoplite, mainly support staff- headed up by SSGt Patterson. Mainly concerned with fire support and base defense, as well as light recon work when required.
Delta Squad- Basically, anyone in CTRG following Operation Deviant, headed up by Athena. She'll be NPC'd, to some degree, and her squad will be mainly working in the dark, to potentially group with FIA reinforcements (I'll keep light on that), as a backup and last-ditch special forces unit for operations surrounding Tempest.
These four squads are what's at Tempest at the moment- 3rd "Crossbow" and 4th "Vanguard" Platoons at Camp Maxwell and LZ Connor respectively are also in the game, though are headed up by Warrant Officers/NCOs, and being eventually wrapped under Huscarl's overall command of the situation. As you'll see, the AAF will really try and gun those two platoons out of their foxholes, leaving our units, under Huscarl's knowledge of the situation at Mike-26, to eventually craft a situation in which the NATO forces launch a last-ditch counteroffensive to get themselves free of AAF troops. But they are outnumbered at least 3:1 of AAF to NATO, so as you can see, shit is grim.
