I serve it just fine from my desk in my cushy little office. You can dress it up however you like but you're being trained and paid to kill poor people, and if you're unfortunate enough to survive long enough to the point where you're no longer needed, you get this wonderful 'veteran' label that comes with PTSD every night and poor job prospects.
My balls aren't made of steel and I'm not adventurous enough to take a bike ride to Reno. But I'll donate from my desk in my cushy little office.
