Echoing a previous comment, I think you may have bought 3 battalions of 105s. A battery has 4 guns and costs ~200, a battalion has 3 batteries (12 guns) and costs ~600. I don't see any way to buy 9 offboard guns. Your force as described costs about 2800 or so (not including artillery), which means your artillery percentage is over 39%! Don't forget, if you have a delay mission, the AI gets 1.5 times your spend(ifrc), so expect to see a 6000 pt force coming your way! I don't recall what arty% an advance mission gets, and I'm too lazy to look it up!
