December 30,2008:  Despite major combat operations in Iraq and Afghanistan, the U.S. Army is going through a major reorganization. The end result will increase the number of combat brigades from 33 to 43. This  required the transfer of over 40,000 people from combat-support jobs to the combat brigades. New equipment for each of the "reset" units costs over half a billion dollars per brigade. Most of this reset is complete, with all the new brigades ready for service in two years.

The reset process has included repairing and rebuilding the weapons and equipment that were used in the combat zone. While there was a lot of combat damage, most of the reset work went for restoring gear that was simply used much more in combat than it would be in peacetime operations. This has caused some serious problems, as much of the equipment dates from the 1980s and 1990s, and was due for replacement after 20-30 years. The rigors of combat has worn out a lot of that stuff way ahead of schedule. The army is scrambling to develop the next generation of vehicles, equipment and weapons. A new generation of trucks will begin to appear in a few years. New weapons and other gear has been introduced gradually, with the specs of this new stuff driven largely by combat experience. One problem area is the new generation of armored vehicles. The FCS (Future Combat System) program envisioned radically new designs for tanks and infantry vehicles. Some of the original FCS concepts are now being reconsidered because of how the M-1 tank, M-2 infantry vehicle and Stryker wheeled armored vehicle performed.

The reforms make the brigades, not the divisions, the primary combat unit. The new brigades have more support units permanently attached, and can be more easily sent off to fight by themselves. In the past, doing this involved quickly adding a lot of support units to the brigade. But the new organization makes small support units part of the brigades, and, more importantly, the brigades train using these support units and learns to work well with them. The divisions still exist, but operate more like the corps has for the last two centuries (coordinating the actions of a few divisions and only having a few support units under its command.)

Divisions now have four of the new brigades, but can control more (or less) in action. Each of the new brigades (or BCTs, for Brigade Combat Teams) has 3,500-4,000 troops (depending on type). There are three types of BCTs; light (infantry, including paratroopers), heavy (mechanized, including tanks) and Stryker (mechanized using wheeled armored vehicles.) This larger number of combat brigades is achieved by reorganizing the combat units of each division into four brigades, instead of the current three. There are several independent brigades as well.

New weapons and equipment (especially satellite based communications and battlefield Internet software) enable the army to get the same amount of combat power brigade, using fewer combat troops. The actual number of infantrymen and tanks won't change, but the number of communications, maintenance and intelligence support will. For example, increased use of robots, sensors and computerized vidcam surveillance systems makes it possible to do the same amount of work in combat, with fewer troops. A lot of these new ideas, and equipment, are being tested in Iraq and Afghanistan, and most of these items have worked well in combat.

This "reform and reorganize on the run" approach has enabled the U.S. Army to leap way ahead of its contemporaries in terms of combat effectiveness. This is causing lots of unease in the military headquarters of the other major military powers.
