Excellent work. If a unit is internal security then it is not included in the game and if military units are formed out of the cadre then you have to determine if it is already in the game and with what TOE %. Good luck with that. The game underestimates available soviet resources.
If we talking about Soviet side, then need to keep in mind that all these soviet units that was used during the war not only typical units of NKO("Ministry of Defense"). There are units of various "departments"(Commisariats)- NKO(typical ground forces ,PVO,VVS),NKVMF (Navy, naval aviation and various coastal forts),NKVD(border guard units, OV,"security" forces, convoy units),NKPS (railroads units), some construction's departments. All of them had their own structures and "pools". Of course with start of the war mobilization of reservists was performed by NKO, but each "department" had their own quota. Also between some influental Commisariats was some kind of rivalry. If necessary units or part of Commissariats's pools was transferred to others(mainly to NKO), e.g. we can see in the game many Naval brigades that was used on front.
I guess for simulation of these separate "pools" can be created separate producible NKVD squad ground element.Atm in the game is unproducible NKVD squad(type - HQ troops) that contains 11 men with 11 PPSh and 1 Hand Grenade - it's too confused. So with new reworked NKVD squad that can be produced under some limits game can be improved in this aspect. Something similar can be used for Naval infantry squads too.
Yes, some players can say why we need to discuss about unknown Naval or NKVD squads, or (what?) NKPS.
But in reality of real total war on Eastern Front everything was used.
As example from the game. In the Riga we can see 22nd NKVD Rifle division that has TOE as normal RKKA's RD. But actually it was formed on basis(by pre-war mobilization plan it should have been 1st,3rd and 5th NKVD rgts) of 5th NKVD Moto-rifle rgt, 83th NKVD RR "security" rgt, 155th NKVD convoy btn and consolidated local rgt(workers,cadets) - total about 4k men total.So was used everything that was around. 30 June 22nd "Division" due to the threat of encirclement and heavy losses retreated from city. Yes, during this battle various remains of retreated units of NW Front was there too.
Using of not-typical units in role of light infantry was standart practice(especially during critical situations), various battalions of workers, militia,etc.
I've also some ideas(as always) about "an adaptation" of some NKVD formations for the game.
