Military term for a 1SG -- the First Sergeant of the company is on top of the enlisted chain of command in the company. U.S. Army and USMC slang for anyone in grade E-8 who holds a diamond symbol in their chevrons, but loosely used also for E-8 Master Sergeants. Term of familiarity, and respect.
"Private Johnson!"
"Yes, First Sergeant!"
"Are you squared away?"
"Absolutely, Top!"
