Infantry Unit Tactics, Tasks, Weapons, and Organization

[SethB]

So, why did the US Army disband the arty bde, perhaps the most lethal formation (especially with today's sensors/technology) in its arsenal next to the CAV regts?

Each BCT has BN of organic artillery, and we have six FiBs that have 155MM cannons (towed or self propelled) and MLRS or HIMARs launchers.
