I don't think you should be able to see all the supply details of the enemy.
I would even consider getting rid of the green/orange/red unit markers, at least as an extra FOW-option.
More FOW is a good thing.

I think it's OK, especially for new or not so serious players. Because all the information is readily available, and you can just could do the math. Sooner or later everyone learns and recalls that supplies ships give 20, regular infantry takes 3, heavy 4, light 2 and transportation 1.

So make it an option.

Edit: There may be supply ships that are hidden, but you still see overall enemy supply I think.

You are supposed to see the supply output, but not the supply balance (small + or - number) for enemy markers. It works for land based supply sources but apparently not for coastal supply. Will fix that.
