I guess nobody picked up on 'division' the independently in the field autonomy strikes a chord with me. But chime in with thoughts and once we get them all together we can have a vote or some such thing.
Division
A division is made up of three infantry, cavalry or armoured brigades. Divisions are usually equipped to operate independently in the field, and have a full complement of supporting reconnaissance, artillery, engineers, medical, supply and transport troops.https://www.nam.ac.uk/explore/army-organisation
