One thing which would make the MMB much more expensive to field is the issue of protected CSS. We could assume the enemy are bad shots like the Somalis, but this is a very dangerous assumption indeed.
Logistics would have to be handled by armoured transport vehicles; using the LAV family as a baseline we would see a LAV III hull converted into a "Bison" type vehicle, or perhaps a "pick-up truck" with an armoured front, and attachment points on the back for various "camper tops" (Ambulance, CP, Fuel Bowser, MRT, palletized cargo and ammunition packages, etc.). As with the other members of the family, these would also have to be fitted with slat armour cages or other protective devices, but only armed with an RWS carrying a C-6 or AGL. Getting around would require armed escorts, perhaps MPs or RPs mounted in armoured HMMVWs or whatever analogue you care to name.
If we have the MMB with two Cavalry teams, one Combat team, a Headquarters company and a Service Support Company, then the Service Support Company should be configured as five platoon sized support packages, one to each company and one in reserve (following the old Service Battalion dicatate of supporting yourself as well). The CSS troops would be well trained in battle drills, and the support model would be fast moving DPs to support manoeuvre warfare as opposed to static CSS hardpoints.
