I honestly have no idea how to approach S3 for my current assignment. S1 is done through a mass e-mail. (Although I have figured out one of the guy's phone numbers. I'm at the Pentagon and he's at Ft Belvoir. My command team is at Myer (wtf?).
My last unit they had normal hours. At Bragg, They worked 9-3:30 doors open. Only Ops Personnel and Command Teams could get in after 3:30 and the S3 SGM kicked everyone out at 3:55.
