The incinerator war droid was a battle droid used by the Galactic Empire around the beginning of the Galactic Civil War.
This droid stood several meters tall, and was armed with a flamethrower and tibanna gas tank along with a large blast shield. The droids were an advancement of the carbonite war droid, but they were developed to house a flamethrower in their "arm" instead of a carbonite projector.
