Had a thought the other day of why not making the Division HQs/Base its' own brigade type. C2/staff/HQs Bn + Signal Bn + Troops Bn (MPs, NBC, local security force units, other odds & sods), + CAV Sqdrn/Recon Bn.[/QUOTE]

This is different then the sustainment brigade?

According to Wikipedia, the sustainment brigade for the 1st Infantry Division consists of a STB, a CSSB, 1DHHB, and 84th ORD BN.
