I found additional information on this topic and seems clear that modularity just costs too much. General Chiarelli has questioned why the Army needs so many vehicles, especially humvee trucks (158,000 by 2012) and puts the blame on the shift to the modular force.

Would eliminating the Brigade Troops Battalion in the BCT and shifting its responsabilities to the Brigade support Battalion help with efficiency?

Would decreasing the number of Forward Support Companies in the BCT do like wise?

Is a FSC necessary for every maneuver battalion or is a 2 to 1 ration sufficient?
