Once shared a bear camp with a last minute addition none of us really knew prior. I agree its best to share camp with those you have previously spent time with.
IDK if we ever served together. I started life as 0311 did a couple years barracks duty in Panama then 2dFSSG at Lejeune where I re-upped and changed mos to 4421. Spent last 5 years at Quantico as instructor/platoon sgt at OCS. Primarily taught land nav and problem solving.
I prefer to remain seated in the aircraft until it arrives at my destination:)
