MANPADS are man-portable, surface-to-air anti-aircraft weapons.  In theBattlestar Galactica RPG, they give stats for the SMI92 “Flying Needle” — essentially the Stinger missile.  The weapon has a maximum range of roughly 15,000′  (about 3.5 miles), and damage of d8W, vehicle-scale.

Similar weapons like the Milan and the Starstrike use laser guidance, instead of optical sighting, and their rockets fly at about Mach 3.  The Starstrike uses a trio of “needles”, each made of tungsten and carrying roughly a 3 lb. warhead.  The Starstrike would have a vehicle-scale damage of d10W (and for Serenity a spacecraft scale of d0W.)
