Some of the most common questions the staff receives from new to 3rd Coast players, "What are these units?" "Why limit the number of roles" "What gives with the different classes?"
I'll break down the units here,
The Rifle Companies ABLE, BAKER, EASY for the Western Forces, and CHAOS, DAGGER, and FIGHT Companies for the Eastern Empire. These are the building blocks for each side. These guys are the grunts, the backbone for the epic MILSIM battles. Each company has anywhere from 2-4 platoons of 25-40 shooters each (depending how their chain of command organizes them for the event). Each platoon has 2-3 squads. In the real military, there is a set number of Support Weapons like light machine guns and DMR/Snipers, so we replicate it here as well (more on the roles below).
The Special Units
For Western, Task Force Darby (and coming this year Task Force Ripper) and the Special Operations Squadron, and for the Eastern Empire, the Airborne Regiment (and coming this year, the Guards Regiment), and the Commandos.
These special units are limited in number, 24 for SOS/Commandos, and 40 for Airborne/Darby. These elements have specific camo pattern uniform requirements that player must meet. The trade off is that these elements have no limitations on the weapon roles they can run (meaning they can run as a DMR carrying an MP7 should they want to hump the weight), additionally, for the 3rd Coast events that have a Recon/Airborne Phase, these players take the field forward, and are capable of being tasked by their Force Commanders to attempt to accomplish battlefield shaping for the main forces. Having unique camo patterns should also help players report what enemy is to their front, and possibly clue them in on what these guys are doing.
The Player Roles
The limited number of different specialty roles forces players to run as a team due to each weapon class having an advantage. The rifleman is the best balanced player on the field, but limited to semi auto. The submachine gun role, having being limited to 300 FPS/1 Joule, is allowed full auto indoors and outdoors, but has less range than all others (being that in real life, a SMG shoots a pistol caliber round and does have less range), the support gunner can lay down suppressing fires with his/her light machine gun or SAW with a higher FPS/Joule limit (and MED), but cannot go full auto indoors. And last, the DMR/Sniper class can provide long distance precision fires with its higher FPS/J limits.
Hopefully this helps answer some of the common questions that players might have.
