But can someone tell me what the likelihood of Full out and out Ground Arty component being a mainstay in the future. If the USAF gets the 22's and others then when comparing ground arty in relation to Air or Naval Arty which are the more likely to be used in largess. Isn't it a little harder for an enemy to take out supporting assets that are in the air or the ocean than on the ground.

Pound for pound what is the tradeoff between these and is it even something to be considered or can our forces not accomplish the missions without 155's on the ground.
