heres an idea, a white phosphurus grenade or tank shell that when detonated, makes a small explosion and using the "Drop" command, create white smokeing particles that fire out, and split into smaller pieces, like, 5 particles that split into 10, than 20, etc, and it should look those fireworks that are called "willow tree bursts" cuz they shoot up in an arc than fall back to the ground... and everything within a certain radius gains damage, and as and extra, they burst into flames (using the fire effect from resistance)
thatd be a really neat addon.
but as a note, realize that wooly pete isnt really an anti-personal device as it is a marking/masking device.
when calling in a fire mission that is "danger close" (ie. so close to friendly forces that it poses a threat, usually 100 meters or less) the radioman will always request "marking rounds", which is wooly pete. the xtreme brightness and smoke created by the wooly pete serves as an excellent marking device, and is much more effective than smoke rounds, because it is visible during the night.
also, when you call in a "battlefield blackout" fire mission (smoke mission), modified wooly pete rounds are fired. the smoke shells are not full of standard smoke grenade composite (potassium nitrate and glucose), instead they contain 14 felt disks that are soaked in a white phosphurus solution.
