I'll give you 6x4 for a Platoon (Cmd, Spt, 4x Close Cbt) = 24).
When employed in the Armoured/Mech role attach the Crews to the Platoons (or the Platoons to the Crews if you prefer) permanently.
Or something like this... (previously discussed)
The British Army’s Experimentation and Trials Group (ETG) have been testing improving future urban operations using a new experimental force concept.

2 platoons of 3 sections of 2 teams of 4 with a 2 person command element in each section
2 Platoons, 3 Sections, 6 Teams, 60 rifles.
Plus a CG84 SDE (Sensor Decider Effector) team (4?) for each Platoon ( 8 rifles)
Plus a Cmd Element for each Platoon (Pl Cmd, Pl 2iC, Pl Sys Op (Pl Medic?)) - (8 rifles)
38 per platoon - requires 6 vehicles or attachment to a 6 vehicle Troop.
And I like swapping the 3rd platoon for the Manoeuver Support Group with its 2 patrol dets with MFCs, its two 81 mortars and its 3 Javelins.
It looks as if the intent is to increase the CO's Area of Influence from the 5 km of the 81mm to the 25 km of Brimstone.
