Infantry stuff:
As I wrote earlier, changed many sections to mixed bolt-action and SMG armament. Some still retain SMG or bolt-action only due to limited number of weapon slots.
No horse cavalry after WW2, I'm afraid. Officially the Finnish Dragoons were permanently dismounted in 1947 and became infantry, but in fact they did not have enough horses for all troopers after 1943. I converted the Dragoon units to infantry, so now they are basically just better than normal infantry, although there probably is not much basis for them being any better than average Finnish conscripts. They still get to call themselves dragoons, though...
Limited the number of units with 7.62mm RK 54 (AK-47). Only 25,000 of them were purchased in the 1950s. That said, whoever got the brilliant idea of separating all the AK action assault rifles chambered for 7.62x39mm cartridge in Finnish service to separate weapons in the game was way over-zealous. They all have the same specs in the game (except the versions with optical sights).
On a similar note, there are separate weapons entries for the DP-27 (also called DP-28 in some English sources) and DPM LMGs like there were significant enough differences between them which could be modeled in the game. The DP-27 also had too low accuracy; it had exactly the same length barrel as the DPM. In any case, all DPs captured by the Finnish Army in WW2 were DP-27s, so DPM should not appear at all. I will change the DPM to DP-27 which fixes the "problem".
Added 66 KeS 12 (M72 EC LAW Mk.I) for some infantry units from 2015. I also changed some of the the sections to 9 men with 2 PKM LMGs (doubled weapon) from the same date, according to a new squad and platoon level organization being adopted. The details are still a bit fuzzy, but 9 men squads with 3 fire teams seems fairly certain at this point.
Some additional trimming like removing a Marksman with a basic M/39 Rifle after 1994. Created a new DMR unit with an RK 95 with optics to replace it (As if there actually were enough ACOGs for any other units than special forces...

)
Changed the names of some units to make more sense of many similar, but slightly different units with the same name and concurrent availability.
