Phew... that's a tough one... Perhaps you could take an idea from another wargame?
Avalon Hill published a game called Main Battle Tank. It was a 'Counter & Hexmap' style game but played very much like minis. A tank counter is one counter, a gun counter one gun, an infantry counter one squad, etc. The setting was the usual NATO versus Pact encounters.
Anyway, the Pact player was constrained by a set of 'doctrine' rules to mimic Soviet combat theories. If he wanted to, the NATO player could push his vehicles singlely all over the map. The Pact player had to keep his vehicles together in the same hex in platoons. Instead of stacking 3 or 4 vehicle counters in one hex, the Pact vehicle counter had a number marker placed on it stating how many tanks, APCs, etc. were in the hex.
In play, these all Pact vehicles in these marked platoons had to fire at the same target. As the 'stack' took damage, the number counter was rotated to indicate the losses; i.e. 4 tanks, then 3 tanks, then 2 tanks, etc.
You could employ something similar to 'convert' Striker's US/UK 4-man fireteams into Russian 10-man decads.
To create a 'decad', you mark a single Striker stand with a chit and then treat it as if it were two Striker stands. They must move together, fire at the same targets, follow the same orders, recieve the same damage, etc. When applying damage, you rotate the marker to keep track of the 'extra' troops in the decad just as you rotate the marker to keep track of the 'extra' vehicles in MBT.
Just mt 0.02 Cr.
Have fun,
