Been lurking forever and found just about everything I ever wanted to know about ARMA, ARMA2, OA, BAF etc..
Lately been messing around with some mission building and managed to figure out a lot about the M252 Mortar.
Funny thing, though. I can load it with ILLUM rounds (adding the Magazine "8Rnd_81mmILLUM_M252") and I can fire them, but I never see any Illumination happening. Interestingly also, when spotting for an AI Gunner, I can get him to fire HE rounds all day long, but once I switch to the ILLUM rounds, he refuses to fire.
Haven't tried the Willie Pete yet.
I noticed that at the current patch level the classnames ARTY_8Rnd_81mmHE_M252, ARTY_8Rnd_81mmWP_M252, ARTY_8Rnd_81mmILLUM_M252 should be used without the ARTY_ prefix
at the bottom of the page)
and that is what I have been doing. Works for the HE rounds.
