I shot right past the C-RAM detail in the article so thanks for pointing that out for us old Redlegs that hang around here. Interesting that the counter-battery mission has moved from FA to ADA but things change and time marches on, I guess. The only thing that gets in the way of this mission is that the enemy usually chooses to launch or fire from a known restricted fire area that’s noted in the US ROE. Thus, the only thing that can be done is early warning for the impact area. That’s only the appearance of force protection, IMNSHO. Real Force Protection occurs when you have rounds in the air responding to the attack before the enemy can leave the area.
C-RAM can engage and destroy incoming rockets, artillery and mortars in the air which is an ADA mission. Actual counter battery remains with FA, however, C-RAM has enhanced targeting data available.
Here is the C-RAM Gun system, aka LPWS: https://www.youtube.com/watch?v=w4PXou0aGiE
With ROE being so restrictive these days a good defensive weapons system like C-RAM is badly needed.
