Fires a small width, penetrating beam that deals high damage. It can pass through terrain and does not arc, ignoring anything in its path. Any enemies that are "stacked" on top of the player will also be hit when the laser is fired. Any friendly tanks will not be damaged by the beam.
Fires an even larger, yellow beam with another damage increase. This is when the laser starts to get a lot of width and is capable of hitting enemies who are slightly away from the rest of the enemies who may be in a line.
