Let's speculate a following kind of structure:
Manouver: 3-5 wheeled ICV battalions.
-Recon: A recon battalion with lightly armoured recon vehicles to create a recon screen and to maintain a presence over a large area. A technical recon unit with UAV's, radars and SIGINT for additional target acquistion.
-Direct fire: One armour battalion, wheeled. Might be also used as a manouver element if situation demands.
-Indirect fire: One artillery battalion, Perhaps 18-24 wheeled SPH's. As much use as possible of PGM's and ICM's to reduce logistical burden.
A forceful intervention to NK or Russias maritime provinces would demand heavier forces. In this case MRB's might be used as follow-on forces.
