What problems did the americans face in providing the necessary supplies and equipment for the war and in paying for them? what were the american advantages and disadvantages in the stuggle?

Thre were a lot of men in the army but not enough money to arm, clothe, and feed them all.

One advantage of the struggle was the introduction of rations. Food was served out in rations and people got no more or no less than what they needed. Less food was wasted and more was available to the American Army.

One disadvantage was inflation. Things were so overpriced to pay for army supplies that the $1 was essentially worthless then.
