Had a think on a revised list, this runs to 1,750 but this is the target for the next event, 6 platoons on the table - and can work reasonably well as 3 on/3 off
Battalion HQ, Sapper Platoon & Reinforcements, Anti Tank Rifle Platoon
2x Strelkovy Companies, each with 3 platoons (2x Rifle, 1x SMG), Kommissar
Heavy Mortar Company, 6 tubes, no observer
Strelkovy Anti Tank Gun Company, 6x Obr 1937 45mm ATG
Tank Destruction Company, 4x ZiS-2
Regimental Gun Company, 4x Obr 1927 Infantry Guns
Then in support and not counting as platoons we have:
Anti Tank Rifle Company, 2 platoons (combat attached to Strelkovy)
2x Flame Thrower Sections (combat attached to Strelkovy)
Air Support, limited IL-2
Thinking the blobs are now large enough to actually assault, and have the tools in the sappers and flame throwers to do the job right, some 37-18 teams in each when they deploy so they will take some chewing through, and one should be able to hold two objectives alone for a while.
The IL-2 is the answer to enemy armour that wishes to sit at range and try to pick off the few guns we have, and also to try and space out the enemy a bit and generally put lone heavy tanks out of position as they force it to range in. Essentially a bit of "reach out and touch someone" ability, that given I've not seen a plane or much in the way of flak all weekend should work ok - the terror value alone is worth something
Regimental guns are naff against tanks, but make excellent little infantry guns in direct fire to dig out the dug in, and 'ok' in defensive fire, rubbish as artillery but conscript artillery seems to be an effort in futility anyway.
Still have the heavy mortars as they seem to scare people, the 45mm ATG are really here as defensive weapons but can be pushed up should the need arise to give a mobile formation some defensive fire v armour (if anyone is mad enough to drive tanks into one of the blobs) and the ZiS-2 are to be hidden out of sight and used to protect objectives from flanking enemy armour (they die too fast to direct long range fire otherwise).
This is 1,750 on the nose, provides each of the two Strelkovy Blobs with:
18x Rifle Teams (casualty markers basically, and bodies to assault with)
9x SMG teams (to do the actual assaulting, and for defensive fire)
4x or 5x sapper teams to scare and attack armour with
6x PTRD anti tank rifle teams - to help keep enemy armour at a cautious range, or at least slow them down for a while
2x flame thrower teams, so when they do go in they have a chance v dug in veterans, and if too much defensive fire is likely can be used in place of the assault to try and remove stubborn dug in infantry directly.
Commander & Kommissar, for giving orders and shooting anyone who fails to follow them
Thus the blob is 39 or 40 teams on the table, and if in reserve arrives all on a single die roll.
Issues
Lacks much mobility, list can't have any cheap mechanised units though, and lacks the points directly to provide trucks for the guns - could drop down to just 4x 45mm ATG which saves 40 points, allowing for trucks on the ZiS-2 and perhaps even four more PTRD to make the blobs even larger
Needs a few bits, but not actually that much, and nothing impractical before the event.
