This dedicated anti-infantry variant is designed for urban defense, and is not for use against other 'Mechs. Each arm has four Light Machine Guns and a Machine Gun Array. It also utilizes a Flamer that can threaten combat vehicles as well as infantry. A single Rocket Launcher 10 provides a one-shot damage potential against armored targets. The 19 has proven popular with Periphery nations and mercenary units.
Mmmm...
4 machine guns per arm.
1 machine gun array per arm.
1 missile launcher.
1 flamer.
so for MWO it would be:
16 ballistic (8 per arm ..since mg array = 4 machine guns)
1 energy (CT)
1 2-tube missile (probably in RT or LT)
