My thoughts are as follows,

Company Weapons.

I can see some merit having a company mortar detachment of 2 tubes. To ease company log issues and to enable dismounted ops, I’d stick with 60mm.

The company can probably also operate a Tactical UAV. It has the staff and C2 function that may well make that very useful.

The best fire support weapon for Platoons is, IMO, guided weapons like Javelin, Spike, or even an update of the old M47 Dragon.

APCs.

An essential piece of equipment which no infantry unit should be without, if required.
Need to carry 8 men, so as to get a useful Platoon load out of 4 vehicles.
Remote Weapons Stations are extremely useful, and if they can also fire the same guided weapon that the Platoon uses then that is also extremely useful.
I don’t care if its wheeled or tracked as long as the mobility capability matches the mission requirement and the most commonly encountered threat, so the same goes for the levels of protection.

I think MICVs are better suited to reconnaissance, so that's a different role.
