Lilian Garcia grew up as an Army brat, while John "Bradshaw" Leyfield is the troops' Number One Fan (real deal). Rick Flair always goes if he's able. Lashley was a multiple year military champion while in the Army.
I'm a bit stumped by Randy Orton going, as he was court-martialed out for AWOL. That boy's truly rotten, having actually dumped in women's handbags backstage as a "joke".
Orton was a bit of a surprise as well, for the reasons you state. *smirk* I think that's one other reason they brought Taker along. Backstage reports around the time of those handbag incidents tell that Taker 'despised' Orton. I'm sorry but that's one man I'd NEVER want pissed off at me...
