An air force is in the ordnance-delivery business, just as an airline is in the seat-delivery business. A TWA jet is well used when it is in the air and all its seats are filled. An F-16 is well used when it is in the air delivering ordnance to a target. The needs of ground people are somewhat different. For one thing, they like to have friendly aircraft visibly overhead. It makes them feel good. If these aircraft are not in fact delivering ordnance, that is not terribly important to their feelings of well-being. For another, ground people like to schedule air strikes the way they like to schedule artillery—hours, sometimes days, in advance. However, modern warfare has changed so greatly, the tempo of war has speeded up so much, and a good modern army is so mobile (you don’t know what you need because you don’t know where you’ll be fighting), that scheduling air strikes in the old way had become seriously counterproductive.

Very early on in their command relationship, Horner talked at length with Schwarzkopf about these issues, and convinced him then of a way of providing close air support that later came to be called Push CAS. That is, aircraft would be designated for CAS, but where, how, and when they would be used would be determined “on the run” by events in the field. If no one in the field had an immediate need for CAS, or if they were holding their own or winning, Horner would send the jets to the enemy rear area. Though the effects of these last strikes wouldn’t show up immediately, when they did, they would prove dramatic. Push CAS required excellent communications and control and also good ways of identifying the precise locations of the targets, but it was not otherwise more difficult than earlier ways of operating. Schwarzkopf had bought into Push CAS in April during the Internal Look exercise, and Push CAS became a reality in February 1991.

The problem of providing CAS to Arab-only speakers was solved by asking the RSAF (Royal Saudi Air Force), all of whom were bilingual in English and Arabic, to provide CAS controllers. It also turned out that there were a few USAF fighter pilots who, by reason of family origin, spoke Arabic. However, neither of these solutions could be instantly implemented. There would have been real problems in August 1990 if the Iraqis had come south.
