Artak gave me this little gem a while back.
Call your player whatever. say... fodder
then make a radio Alpha trigger and put this in the activation,
bomb1 = "laserguidedbomb" camcreate getpos fodder
it rocks.
You could also make a uaz and call it fodder. make the radio trigger as usual and then blow it to bits.
I use it for mines sometimes.
You can camcreate just about any explosion with it. Look in the Ed depot for the weapons and ammo list and play with different bangs. ;D
