Sorry for the confusion. Btn Commander was made way before NUTS Big Battle, and was done to blend with Platoon Leader and Star Army
. Just like Star Army isn't
NUTS in space, the same thing with Battalion Commander.
As for not seeing the difference between BC and 2nd Tour, you could take a short cut and look at the QRSs of each to see the big differences such as shooting melee, mech combat, etc..
If it isn't what you expected no problem, just email me at firstname.lastname@example.org
and I'll replace or refund. Hope this helps,
