In 1942.2, hypothetically you can squizz higher value units if Germany and Russia would have double IPCs economy:
Russia can only built (Moscow IC 8+ Caucasus IC 4=12 units) Max: 36 IPCs
Germany: Italy IC 3+ Berlin 10+ Karelia IC 2. Max: 45 IPCs into Infantry.
So, you have to reduced ICs production cap with Global.
10 per Major should be reduced up to 5 per Major.
Countdown: 11 units minus Rnd nb. 11- G1 = 10 units max.
G1 = 10 units, (G1+10 = 11)
G2 = 9 units,
G3 = 8 units,
G4= 7 Units,
G5= 6 units,
G6= 5 units.
For SBR, just consider additionnal IPC considered as damage. To built, after G6, if maxed out, 15 damage points have to be repaired before paying 1 IPC to build 1 unit.
The only way to increase production would be to built another Major elsewhere.
Minor stay 3 units.
Japan, England, Moscow, might submit to this rule, not India…
