Expanding Charles Grant`s "Battle" rules

In Charles Grant`s original rules he organised a rifle company thus -

3 x 9 figure platoons each with -
Officer/NCO, 2 SMGs, 5 riflemen and a support weapon (Bazooka or light mortar) with 2 crew

Thus a rifle company had 27 figures.

We quickly concluded this missed out one very important weapon - the light machine gun (LMG), we also realised that 9 being an odd number doesn`t split well for fire-movement infantry tactics, so our company evolved -

3 x 10 figures with -
Officer/NCO, 2 SMG (or Grenade throwers), 6 riflemen + support weapon (LMG or light mortar) with 2 crew

Company strength now increasing to 30 figs; you will also note we dropped the Bazooka (or Panzershreck) as these migratedn to became part of the Battalion HQ company's anti-tank platoon. The new layout allows you split your platoon with half covering, whilst the rest advance an leapfrog fashion.

This worked for a while, but we felt the command/control element was missing (at company level), we then tacked a company HQ on -

4 figures - CO, NCO, RTO, driver/runner

Your company strength now increasing to 34 figs! But gains, a central command element and communications to higher level units/support.

At this point we started tinkering with national variations and period changes:

Late-war Germans
Platoon strength - due to loses late-war platoons loose a rifleman and drop to 9 figs
Panzerfaust AT weapons - we doled these out 1-2 per platoon as one-shot weapons.     
Extra LMGs - replace 3 riflemen with another MG42 team (reduced strength, increased firepower) 
Drop Light mortar - replace with MG42 team

US infantry
BAR - replace 1 rifle with BAR
Support weapon platoon - US infantry units changed massively -
HQ
3 rifle platoons - officer/NCO, 2 SMG/Grenaders, BAR, 6 riflemen
Support platoon with - .30cal team, Bazooka team, 60mm mortar team, 4 rifles (ammo bearers)
US company strength now 44 figs!
