When I was a detachment commander, I did the same thing. An A team is populated with senior NCOs for each specialty. Being responsible, professional guys, they kept the equipment in top condition and accounted for it. The team leaders that micromanaged it were the ones who had the accountability problems. Most team leaders who demanded to have a close leash on equipment gave up after the first time they tried to inventory the surgical and dental kits.
You'll have an E-8 and 5 E-7s to keep things straight. If you get there, use them. Just tell them what you want done and they'll figure out the how, usually trying to out-do the guy next to him. It's one of the best ways you can establish an atmosphere of trust between you and your NCOs.
