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).

Latest version of CSLA Mod for Arma 2: Combined Operations has been officially released.

This release closes another chapter of our work.
We will no more come back to this version of Mod, because we found that the interest of the community for an CSLA Mod has decreased significantly.
Also, this led us to the fact that for the final edition of Mod, we canceled planned second campaign and additional vehicles for AFMC and FIA (various versions of M113, LAV-25, BTR-50, ...).

Anyway, in this final release, you will find an improved MP COOP mission Protectors in version with CSLA playable slots.
This mission includes several new playable slots available for partisan units FIA - if players will occupy these slots, they can significantly and actively mess up the tasks for "normal" CSLA players.
Info about this version of the MP mission is also linked to another novelty - a completely new characters of FIA guerrillas.
They have a new fatigues (pattern is called MLOK) and they are also available to carry any type of backpacks, which doesn't allow the original game.

This latest version of the Mod is completely full package of addons and other additional stuff (reference guides and manuals), so you don't need to apply any patch - just run the installer which will take care of overwriting of old PBO files.
As in previous release of Mod, was published also a huge campaign '89, the updated version is also included in this last release.
We did there a lot of corrections and adjustments, so we hope that you will return to the campaign again and try it "survive" it again, but for example with another end of the story.
If you will be in any kind of troubles in a campaign, you may look into the installation directory of Mod and there you may find a very detailed campaign flowchart, which clearly shows the flow of missions.

As an additional bonus to the latest edition of Mod, you may also find (in the installation directory) a small ZIP archive, which contains various versions of DVD cover.

And what will happens with CSLA Mod in Arma 3?
Given the minimal interest/community support for our work, we consider to do a radical solution - we will do all Mods only for our private purposes and our own pleasure - as we are already doing now.
But who knows ... maybe something will change in the meantime :)

Oh this is too good to be true. I've always liked Slavic armies, and it's always something special when they're given the attention they deserve in games.
As soon as I get a computer that doesn't suck, I'm getting this mod!

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.
