The only real snag with it is it should be applied across the board to all nations, also it could be argued tank crews are better than AFV or truck ones.
I have noticed quite a few things that have crept in as diffrent people have a go at OOBs, its a lot to check before saying its correct.
Now this might be due to National traits which is what I think the experince rating is a partial reflection of.
Take for instance as can remember South Africa its set up with very good C&C giving extra rally chances.
You can buy a Mech Platoon which has its own Company Leader, forget the name & no doubt tryiing to represent a special formation.
Its artillery to is arranged nicely allowing you to buy in 2 groups of 3 or 4 with the first unit a Company Leader. Very handy now you can cross attach other support elements like AAA to him. Yet most nations will come as a battery of 6-8 units not 2 troops one being the Leader.
If you buy ATGM jeep type vehicles as a company they come as one lump so a large platoon & being a company makes no diffrence except you can cross attach & add even more units!! Yet the stock
USMC version comes with them split in platoons, this I agree might be because they are a staple vehicle in that force.
As I said it may be done on purpose in some cases to represent a good or poor command structure like the WW2 Russian tanks, its certainly nice playing the likes of South Africa because it is a flexible force due to the number of Company Leaders.
