Long campaign replacement points

[Flakjacket]

I have played about a years worth of battle for the American long campaign and usually get 75 replacement points after almost every battle. Needless to say, by the time Operation Torch rolled around I had a skeleton crew and two tanks to start off the invasion.
Is there a way to up the replacement points for the long campaign. I find it hard to believe the Americans could not even replace two Shermans after every long drawn out battle.
