Staff cannon

Stationary field weapon used by the Jaffa for large-scale combat operations. The staff cannon is a larger and more powerful version of the staff weapon and death glider cannon technology, delivering a powerful blast of charged plasma at its target.

Like the staff weapon, the head of the cannon is enclosed in a four-part casing. The four segments open with a crackle of energy when the device is made ready to fire.

The cannon is mounted on a large tripod base, which stabilizes the weapon during operation and allows it to be turned 360 degrees for target acquisition. It can be deployed into the field of combat relatively quickly, and is operated by a single Jaffa using two handles.
