I have 2 ideas for scripts:
1. A throwable weapon like smokegrenade that's only ONE of the 4 night time extraction smoke/flares that's put on the ground when you request a nighttime extract with mh47. In short: a trowable smoke/flare rolled into one.
2. A script activated through the action menu for camcreating the 4 smokeflares, with the take-weapon-drop-weapon-animation to make it seem the unit does it... in short: camcreate thru action menu the 4 bas smoke/flare markers for extraction day/night.
Not really any use for SP, unless you are the pilot of the extracting/inserting helo. Great for MP, I guess.
