Laser Lance
From Warhammer 40k - Lexicanum
The Laser Lance is an Eldar device used by the Shining Spears Aspect when charging into combat. It uses highly focused laser beams to devistate an enemy unit before charging in for the kill. They are very short ranged requiring a dangerous proximity to the enemy although the speed at which combat is fought while mounted on Jetbikes means they can get in an out again within a few seconds.
