Plasma cannons are the most dangerous weapons Martians and their robots wield in combat. It would be great if our troops could use them.
Plasma cannons work in two modes. They can either produce a big ball of plasma, which is sent to hit one specific target, or they create a cone of hot plasma, which sweeps over everyone in its way. The cannons are constructed to be used by Martians, so human soldiers may have slight problems in operating them.
