well a former 31R here, which was a multi-channel system operator maintainer back in the day (signal corps)

Stationed at Ft. Lewis, WA - home of I-Corps - which if any of you are old enough to remember the TV show MASH, well whenever Radar called I-Corps and spoke with Rosie, that was FT. Lewis, yes we are direct support for Korea, which right now would be a bitch, considering all vacation and everything would be cancelled and they are probably on 24 hour jump notice still with Lil Kim over there in charge now.
