A full strength US Inf Div requires 1,100 tonnes per month or c 39 tonnes per day
In combat mode and under attack that requirement doubles so 80 tonnes per day and 2,200 per month
A Div has c 13,000 men so roughly 220%
For every 10% overstacked supply requirement goes up an additional 20% for every unit on the atoll.
So base Supply 1,100
Penalty Supply 22 - 10 x 20% i.e. 240% supply penalty
So that Div now requires 340% of normal supply or about 3,800 per month
In combat that means it needs 7,600 per month actually thats a lot.....
A div in all honesty is just about liveable with on an atoll its tight and cramped but just about doable....
Now 2 Divs = 26,000 men thats 440% overstacked ?
So thats 44 - 10 x 20% or 680% supply penalty
So thats 1,100 x 2 Div = 2,200 x 680% = c 14,000 suply per month or 28,000 in combat mode.
On attack I never bring more than a Div on defence I will run to about 20 or 30% overstacked if I must but I dont like doing it.
