Hmm...they tend to throw grenades when there's no-one apart from their target(s) in their line of vision...I don't think the script will make them throw a grenade...the mp5 scripts don't do any damage...they just flash and make a noise. Also, to everyone: get Jed's HLMV (There's a link somewhere on
http://hl-improvement.com). It's an improved version of the original, which supports transparency, and it has a greenish background instead of black, so you don't have to change the BG colour to make the model easier to see if it has black areas.
