Could the devs make a grenade-like device (thrown) that would provide vision in an area? It would be great to be able to toss one in a room (or on top of a building) to check if I'm about to grenade a civilian instead of an alien. Plus it would make sweeping the map for that one last alien easier. Your troops could drop one every now and then for "cleared" areas to save time backtracking. It would also make it more difficult for aliens to sneak up on your troops when advancing or sniping. The device wouldn't need to last long (a few rounds) and only provide vision in a area a bit bigger than a plasma grenade or flashbang.
