That one boardgame SQUAD LEADER by Avalon Hill which I have mentioned before on other threads, had a scenario called Pavlov's House. You might want to use it as a reference if anyone gets around to making a map of it.
Obviously, I wouldn't copy the Scenario description verbatim word for word or anything like that.
But since this was a historical event, this may give you some ideas for your own RO version of the events.

The 2-3-7 units in SQUAD LEADER were tank / artillery crews of 4 men, and the RO Tank Crew Role would cover those soldiers.
The other units are squads of 10 infantrymen. 4-4-7 are riflemen; 6-2-8 units are PPSH sub-machineguns (they never really specified; nades were considered included in the unit's firepower); the 3 numbers respectively represent firepower, fire range, and finally something called morale which was unique to the game.
I imagine the higher firepower and more limited range had to do with the type of gun being used (which would make sense), as opposed to the men's individual strength and military experience, although that could have been a factor as well).
The individual standing soldiers were the Squad Leaders; the unit with the soldier lying down with the rifle is an individual Sniper.
The Light Machine Gun (LMG) is equivalent to the MGs on both sides in RO. IN SL, the LMG became a Heavy Machine gun (HMG) Unit if it was considered to be mounted on a solid tripod, with plenty of ammo and barrel changes, and fire around 1,000 Rounds Per Minute (RPM); if it was set up with a bipod and a small cylindral drum of ammo, it could fire 150 RPM; they don't really explain the MMG, but it probably means the gun has less ammo available.

Scroll down, and click on Pavlov's House in, towards the end of the Cross of Iron section of the scenarios in the middle of the page.
You will be able to read the scenario; all you need is Adobe / Acrobat Reader which you can download for free if you do not have.
