Deployment Buddy

A friend that is a supplement for companionship while away during a long work related period. This person has no intention of remaining friends upon returning home.

Reginald: "I'm so happy we are finally home from overseas. Do you want to go to the bar and hang out?"

Victor: "Listen, I can't feel the bromistry between us. I don't think you and I can be pals. You were only a deployment buddy."
