Missing a Few Missiles

Missing a Few Missiles is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
After successfully completing the quest Ant Misbehavin', return to Raquel. She mentions having another job for the Courier, gathering missiles. They're used quite a lot, and as such Nellis Air Force Base is low on supplies. She would be grateful if the Courier brought her some.

Scour the Mojave Wasteland for them and return to Raquel to gain more Boomer fame.

One is able to buy missiles from vendors like Alexander at the 188 trading post, who specializes in firearms equipment, but for less of a profit. High level areas may hold missiles, and is more commonly found on enemies that may hold a missile launcher such as a sentry bot. A few missiles can also be found on the base itself.

Bugs
It may be impossible to obtain this quest if you either finished the Volare! quest before Ant Misbehavin', or Raquel didn't spawn due to entering the Nellis Air Force Base by other means than the front gate.
