Larry Harris's 41 Global set up

It is more realistic to move warships from one SZ to another.
But, would you retreat more than 1 TT to repair your Tank?
(Land movement are much slower and falling back damaged Tanks while staying in position with Art and Inf make such delay an issue. You also have to compare between planes for the cost. Aircraft mobility and versatility is way more interesting than 2 hits units which have to return to IC for repair.)

IMO, it is easier to consider that such unit are repaired right on place with spare parts.

A different procedure I suggested a while ago is that you can only repair one and have to pick a damaged Tank as casualty before allocating a hit to damage another Tank.

So, instead of 10 Tanks staying on battle until the 11th hits.
A second hits eliminates a first Tank.
This becomes far less effective, but it is easier to follow a single damaged Tank per stack.

However, I did not search on how to calculate such way of allocating damage.

Update -

Combined UK Commonwealth Nation

Works great! Played it out and it seems to be balanced and it allows for greater viability as the Allies.

US Rules -

The 2 IPC’s taken off from buying a bomber in Western US works fine and allows for some historical accuracy

The Free French

These units now move with the Commonwealth and attack and defend along with them.

Vichy France

Now moves with Italy instead of its own turn

NO’s

The NO’s are now an optional addition and you can pick and choose which ones are played in your game

Corrections

SS/Red Guard/Rangers/Commandos should move 1 instead of 2.

Canadian Sub starts in SZ 120 not 101

The Spain rule hasn’t come into play, as the German player has not been able to roll a 6, more on that later
R&D works like a dream and creates new tactics for the powers

Lend Lease

Gives the Russian and UK Player a better chance against German and Italian Aggression - Works well

Good point. I originally did this to balance the fact that Germany gets an AA gun for every coastal territor making it tough for the Brits to invade. Only way to balance was to make it tough for Germany to invade. Also keep in mind that this is a part of a setup that adds tons more units. For instance:
North Africa: Germany: 3 infantry, 1 mech, 1 artillery, 1 tank Italy: 2 infantry 1 mech, 1 artillery, 1tank.
Egypt: UK 2 infantry, 1 artillery, 1 mech, 1 AAA, 2 tanks, 1 T bomber ANZAC: 1 infantry,  1 artillery France: 1 infantry.
Allies get more in Middle East and Africa and Axis have three transports in Mediterranean. I really should post the whole setup.

I was actually thinking about this at work tonight. It could be a really cool concept.

And instead of giving the US an extra $10 for having the Philipines and Hawaii, they should start off with $10 extra and lose $10 due to a massive loss of morale when they lose them. A penalty as suppose to a reward. The loss of morale can truly result in a loss of production. That would make it more realistic.

I am probably going to post this topic in another section. I would like to build more support for this for any future revisions to the rules.

Global 1939 is really based on AA50 on sea, and on land entirely new concept ( though for some reason the AAE40 map has some bearing to mine)

And yes this goes to house rules
