I have a very detailed death-by-powerpoint briefing at work, but this is the best I can find on the
web. Note the 4 "units of action" on the right side-bar instead of the 3 brigades that were there previously. You cna click on the UA names & see that each UA has 2 maneuver bns & 1 cav/recon sqdrn versus the previous 3 maneuver bns; that each UA has its organic arty & engr & CSS ertc vs the old centralized system where such units were farmed out from DIVARTY, DISCOM, and so on. None of this stuff is classified, so I bet its on the web somewhere, but globalsecurity.org is the best I could come up with.
You cna click on the UA names & see that each UA has 2 maneuver bns & 1 cav/recon sqdrn versus the previous 3 maneuver bns They don't have a cav/recon sqdrn(squadron). They have a cav/recon troop. That's the same difference, for practical purposes, as the difference between a battalion and a company.
Please forgive the correction. Again, thanks for the link!
