The T-7 ion disruptor rifle was a type of powerful energy weapon, designed to disable vehicles. A single shot could disable a Starship or topple an AT-DP walker.
Although conceived as an anti-vehicle weapon, the T-7 disruptor had very gruesome effects on living creatures destroying them atom by atom. This led to the Senate banning the weapon on humane grounds.
T-7 ion disruptors were once used by the Empire against the people of Lasan when they attacked the planet. Few Lasats survived and none remained on Lasan. The order to use them was given by ISB Agent Kallus, who boasted about it to antagonize Lasat survivor, Zeb. Despite the Senate's ban, the Empire was shipping those Disruptors as prototypes so they could mass produce them on Lothal.
