WM: but it will easily be overwhelmed when the information (I meant that, not intelligence BTW) firehose from above is turned on to beef up SA at the company level
That is not happening and that is the point. The traditional higher to lower in this fight does not work. That was apparent before we "transformed" the BCT; that transformation certainly complicated life. The company effort is centered on its AO and it drives the continual assessment process.

ODB: I personally am having a hard time accepting the fact you need company level intel cells. Very few units in the Army push missions up vs. missions being pushed down.
That too is happening as astute S3s at BN pick up on the fact that their line companies have the best operational grasp.

Again, I will suggest that if you have access you go read some of the material on this subject. If you don't have access, look at CPT Gwinn's article as an example. It is here on SWJ.
