This trick works for primary weapon only, at least that is what I have found. First, set your multiplayer weapon preferences up. Then, when you have the desired primary weapon chosen, go back and select single player. Choose your mission, but do not press the right and left arrows next to the primary weapon on the weapons confirm screen. While the mission loads, the bottom of the loading screen will say you have the default primary weapon, but when the mission loads, you will have the primary weapon you have chosen.

First you get a AT4 out then go to a grenade luancher aim your AT4 at the floor just infront of the Grenade luancher nad fire as soon as you fire press the shift key when you press space bar after you should respawn back at the nade launcher instead of the spawn point.. This takes time and practise and don't shich weapons after you gto it right because you lose it then... and if you get killed you have to do it again...Have fun with this one...
