A couple of rules ideas

[sleipner]

Hi, another way to go regarding Home Guard etc. could be to say that flagged terrritories has a notional unit (yes, I too come from a WiF background) with a defense value equal to the PP value of the territory.
     So 1-5 is what to roll equal or under for a hit, a 6 equals a hit, more than 6 equals a hit + a chance for one more. So for Ruhr, it is 1 hit and 1-4 for one more. This unit could not be taken for losses and fires only in the first combat round and only the first time the area is attacked.
 
Positive: no more units needed and restricted influence in combat with many units (except perhaps US that has few and high-numbered areas, maybe max out at 10?)
Negative: remember which area that has used it´s notional unit. Especially in Russia if the war goes back and forth will be troublesome I guess. Anyway, only a suggestion.

It may be easier just to say EVERY territory must be occupied by a ground unit in order to collect income.  That would force Germany and the UK to leave garrisons in their home territories as well, in effect creating a Home Guard.

No homeguard, you leave it empty, you take the chance. No every home territory must be occupied.

If this, then the max builds on infantry need to be increased; because I think they are right on as is.
