Some of you seem to have overlooked attack helicopters as providing close air support/airborne fires. As this is the Military Aviation forum, such an oversight is not well played.
The 2.75 rockets are now able to fired in guided mode. Hellfire has its bugs worked out. Apache/Cobra others have mounted guns. (No, nobody has the A-10's gun, but there's more to CAS than a gun). A variety of nations have comparable munitions. If you need airborne fires, you don't need a bazillion dollar jet, nor any jet at all. Call your local helicopter battalion or squadron. (OK, if it's a Tiger, make sure they are flying that day. *Evil Grin* )
PS: I love the A-10. A lot. Hawgs is good.
