i was playing a QB and i decided to go all out with arty spotters. i got some 150 rockets, 105s, the works, about 10. i placed them forward and had about 3 trp's placed evenly across the map. so i start the first turn realizing that i put my spotters on top of an EXTREMLY exposed hill. the enemy pounded 7 of em to death in 2 turns and the other ones broke, but strangly enough, the rest of my force was almost completly intact. so in summary FOs draw fire extremely well (will work with stupid 2" mortar teams too) and if you have one thats out of ammo or you dont really need send him up front to taste combat!
