In the Army, with the old Class-A uniforms, was an E-3 in an E-5 slot, exercising the duties of a team chief, authorized to wear green tabs?

The reg and the ALARACT 062/2004 both indicated that a person assigned the position of team leader, was authorized the green tab, and had to remove it when no longer holding the position.

I interpret that as a "yes" if you were placed in that position by your leadership.

But, it's a moot point now with the current dress uniform. Why are you asking?

Never seen a SPC or below wearing a Green Tab, we also wore them on the field jacket and gore-tex jacket. The soldier would have to be properly slotted in that MTOE position, that wouldn't happen as the unit would not receive a Team Chief Pos because the slot is filled. Now at the Company they can have that PFC cover down on the right until they receive a Team Chief for that slot, but that PFC is not slotted in the Team Chief Pos.

Since we're talking about the old Class A's, if you look back to a relevant edition of 670-1, (2005, section 28-21 on pg 242-243) it states the tabs are to be worn by those in leadership positions, and per subsection d, removed when no longer in a leadership position. it says nothing about a minimum rank, which would square with my own experience when I was an SPC4 and held team leader and squad leader positions, and wore them. I hadn't run into any E3s in an actual team leader roll, but it could happen insofar as I know.
