"
Standard BattleMech armor is composed of several layers providing various degrees of protection and support. The first layer is extremely strong steel, the result of crystal alignment and radiation treatment, which is also very brittle. The second layer is a ceramic, cubic boron nitride, which combined with a web of artificial diamond fibers acts as a backstop to the steel layer. These two layers rest atop a titanium alloy honeycomb structure which provides support, and a layer of self-sealing polymer sealant which allows for space and underwater operations."

"In the BattleTech universe, armor is ablative in nature. This means that it is generally destroyed or blown off when hit, but in the process of doing so, it absorbs enormous energies, protecting the unit it is mounted on. While powerful blows will still rock a vehicle, there will be little, if any, internal damage as long as armor plating still remains. Armor-piercing rounds do exist for certain weapons, but they require a higher technology level and cost more. As a result, destroying a 'Mech requires either immense firepower, concentrated fire on a vulnerable location, or a lucky hit."
As previously noted, the laser cutter uses a blast of air to remove molten metal from the piece being worked.

those are also only medium class lasers, they are supposed to be little popgun weapons so it looks fine hit em with the red ones (large) i bet they will leave bigger holes
For MWO:
Red beam = Small Laser
Green beam = Medium Laser
Blue beam = Large Laser
Blue bolt = PPC
