What equipment do FO's/FOO's/FISTers commonly use and how is such a team structured?

I was a FO Officer for a light infantry battalion. It sounds about the same. For a Infantry or Tank Company you have a Lieutenant and Staff Sergeant along with their Radio Operator at the Company HQs and a FO team consisting of a Corporal or Sergeant and a Private with each rifle platoon. Gear sounds about exactly the same.
