Bringing on German Reserves

Folks,
Hope this has not been asked too many times before (I did check, Honest!)

When bringing on German Reserves does a Platoon of Infantry count as:-
a) A single entity for all elements,
b) 1 Command section, 3 Combat sections and up to 4 Supports - totalling 8 max
c) 1 Command Section, 3 Rifle sections, 3LMG's and up to 4 Supports - totalling 11 max

Guidance much appreciated. I understand orders once on the table are as per c, but just wanted to verify how to bring on from Reserve.
Thanks

c) 11 units if on foot.

But in most cases they would be mounted in some sort of transports, reducing it to 4 (4 trucks, half-tracks, etc.)

Best Regards,

Diego

Wait a sec... Does this mean that when I roll reserves for my Canadian Armoured Division I can take all 3 Shermans from "Sherman tank troop" tank unit as a single choice at once?

Nope, it is three units in game terms.
