This build is primarily an LRM boat. It has enough ammo to keep pew pewing for a while and with only 3 LRM 15s you aren't getting any ghost heat so you can group fire away and reduce the number of missiles being cut down by AMS, When the ammo bin runs dry there is a trio of large lasers to rely on, but this build runs hot if you use the lasers and the LRMs at the same time. The machine guns are there for crits when the enemy closes (and with your speed, they will). Overall, there are other mechs that throw out better LRM goodness, but they don't pose much of a threat inside LRM range or once the ammo is gone. Three large lasers won't be enough to win a 1v1 against another assault, but it still packs a hefty blow and is pretty concentrated being from the same location.
