Question. Do the extra CS weapons that are situation dependent have to be integral to the Platoon/Section and available when needed, or can they be attached/detached from above as required. I mean at a level beyond the normal Platoon/Company Weapon Detachments and Battalion CS Company?
Almost along the lines of the
Machine Gun Battalions of WWII. A Brigade-level resource that could see additional CS Companies attached to Battle Groups as required by Brigade. As Company-level attachments they would presumably see a better coordination of effects than individual Section/Platoon support weapons operating the same systems in greater isolation.
This could be an ideal role for Reserve units as they would typically only be required during major combat operations. It would allow units to concentrate on specific skill sets.
I know it's a bit of a thread derail, but how the Sections and Platoons are organized depends greatly on what support they can expect from echelons above them.
