You missed a good amount since 2014.
Namely, we're a hell of a lot smaller than we were back then, in part due to the fact that the 9-year-old Arma 3 doesn't attract many new people anymore, and because we're far from the only game in town with regard to serious milsim.
I believe we peaked around the time you left, at seven rifle platoons and two weapons platoons (plus a section in G Co), a tank platoon, an AAV platoon, a LAR platoon, an artillery battery, a force reconnaissance platoon, and six aviation squadrons totaling thirty-four aircraft.
We're now two rifle platoons, two task-organized weapon sections, an ACV platoon, a MARSOC team, and two aviation squadrons for a total of six aircraft. In truth though, this just means less paperwork - the number of positions on a server hasn't really changed, we just host two task force servers instead of eight.
And Calais is still head of the BAS.
