Have you ever wanted to get rid of that empty, bulky and heavy rocket launcher slung over your shoulder?
Well, now you can, if you've installed OFP: Resistance.
OFP: Resistance lets you drop weapons and weapon magazines and also lets you load weapons into vehicles.
If you don't have OFP: Resistance installed. then tough! There is no direct command to just dump a weapon without picking up another one. The only work-around that exists in older OFP versions is to find an M60 or PK machine gun to pick up. This will drop both your primary weapon and your launcher. If you don't want to keep the machine gun, you can then pick back up your primary weapon and you'll have given the rocket launcher the slip.
