scale invariance revisited

Last month I pondered what was involved in actually sending in those extra combat brigades.

Apparently I am not the only one

Congressional Budget Office plays scale games too

To reflect some of the uncertainty about the number of support troops, CBO
developed its estimates on the basis of two alternative assumptions. In one scenario, CBO assumed that additional support troops would be deployed in the same proportion to combat troops that currently exists in Iraq. That approach would require about 28,000 support troops in addition to the 20,000 combat troops--a total of 48,000. CBO also presents an alternative scenario that would include a smaller number of support personnel--about 3,000 per combat brigade--totaling about 15,000 support personnel and bringing the total additional forces to about 35,000.
