Military Units should have dedicated storage, It's been suggested forever, and most people tend to agree about that.
If this ever happens, I think there should be the availability of supply based Campaign Orders for MU members.
For example, as MU Commander i can set a max supply of 25 (or more, just an example) q7 weapons for a battle. If a member accepts the CO, and does 250 hits they would deplete their share of the supplies. If another member does 100 hits, then they get 10 of their 25 max weapons. This is a very fair way to supply. It gives military unit members the potential to gather the same amount of "pay" because it's not based off of strength like the current currency CO option. This concept could also allow food as a payment as well.
