Get ALL Weapons (Operation Anchorage)

Here's a sneaky trick to get you new weapons and also keep your old ones. What you do is drop the weapons of your existing kit on the ground before you talk to the quartermaster and instead of taking them back and issuing you new ones he won't be able to take your previous kit from you so he'll just issue you new kit.
