I saw graphic sex talk, guys (and occasionally gals) playing multiple people at once (sometimes on the same shift), one friend of mine who bragged about blowing the ENTIRE fire department on Al Dhafra (her husband was an F-16 maintainer deployed there at the same time), graphic descriptions of one woman's menstrual cycles, the commander is stupid, this or that officer is stupid, this or that chief is stupid, "meant to send a whisper but posted in a theater monitored and available channel" more times than I can count, R&R plans that slowly fell apart, marriages falling apart, couples arguing, shit talking people, amazing gossip about their sexual habits including closeted homosexuals...
And the best part? They thought wiping their chat window deleted it from the server. Nah, the second you hit that entire key it wrote to a text file.
