 There will be supply caches located in the city, but whatever expenditures you make in a fight would deplete her resources, possibly rendering her very vulnerable until she can resupply.

all that is reasonable and basically what I was thinking anyway. The whole having to leave and get supplies also leaves her open to ambushes by melee characters when she returns from a supply run or having the enemy find and them occupy the cache, causing a stand off as her fuel slowly runs out.

would you want me to record the supply counts she has during the rp or go on a "she used a butt tone of bullets there, so she's probably out" basis. the second leaves it up to running out when it would be most dramatic which is probably better for writing purposes and stops my opponent and I from having to do bullet counting. In either case I should probably list the ammo counts per clip on the sheet so we have a general idea of how much firepower she can sustain.
