History of real CSLA:
The Czechoslovak People's Army (Czech: Československá lidová armáda, Slovak: Československá ľudová armáda, ČSLA) was the army of the Czechoslovak State from 1954 until 1990. On March 14, 1990 the Army's name was changed to the Czechoslovak Army removing the adjective "People's" from the name.Since 1955 it was a member force of the Warsaw Pact. The force was split into the Army of the Czech Republic and the Armed Forces of the Slovak Republic after the 1 January 1993 split of the two states.

The ČSLA was composed of Ground Forces, Air Forces and Air Defense Forces.

Ground Forces
Ground troops were the largest component of the Army. They contained infantry, supported by tanks and armored vehicles. Czechoslovak military doctrine demanded large tank columns spearheading infantry assaults. While the armored columns secured objectives, the infantry would provide close support with mortars, rockets, anti-tank guns and large artillery. Infantry units could also draw support from engineers, artillery, chemical troops, railway troops and paratroops. Additional services and equipment provided the combat services the necessary technical and material equipment they required. Engineer troops were equipped with road and earth moving machinery, recovery tanks and equipment for the transportation of troops across rivers and other terrain. Railway troops were able to provide construction and rehabilitation railway, including bridges and communication and security equipment and maintenance rail vehicle.

Air Force
The Air Force was equipped with supersonic jet fighter aircrafts, attack helicopters, missile weapons and electronic equipment. Its command formations were the 7th Air Army (air defence, two AD regions) and the tactical 10th Air Army in Hradec Králové.

Air Defense Troops
The Army's air defense (PVOS, Protivzdušná obrana státu) was formed with anti-aircraft missile units, interceptor fighter aircraft, and special services radio-technical units (radar and direction-finding).

Try to search before asking. The answer is already here for few times.
Anyway ...
AFMC stands for Armed Forces of the Midland Coalition.
Militray coalition of countries which are in the neighbour of Chernarus.
All these countries are West/NATO oriented (but not a member), so they have also mixed equipment of West origin.
Play the SP campaign ... you will find more.

Exactly ;)
Arma2 is extension pack for Arma2:OA (not vice versa).

I know, I was going to order ArmA 2, but it was out of stock so I had to buy only Operation Arrowhead, since I knew it was a standalone expansion so it would work without the original ArmA 2 client.
