On H&K's comments on the G36 failures that the gun wasn't made for prolonged fighting. I am reminded of the US civil war procurement story that the reason the heels fell off the boots was that they were made for the Calvary and not the infantry.
On using F16s for CAS. Unless you have a FAC or 20pds of eagleview gear, you are screwed. Anyone remember ground units in Iraq trying to mark their location with penflares and smoke? Eagle drivers are too high and fast to get a visual.
