Octuptarra magna tri-droid

Tri-droids were Separatist war machines used during the Clone Wars. They fought on worlds such as Mygeeto.

Characteristics
Equipped with chain-fed ordnance launchers, these three-legged artillery droids were formidable in battle, taking on infantry and tanks alike. In addition, the tri-droids could scale walls, which meant they could reach places most ordinary armor could not. One rocket could blow up an UT-AT, if aimed correctly.

These are not to be confused with the Separatist's flying droid tri-fighters.

History
On Mygeeto, tri-droids were used against Jedi Master Ki-Adi-Mundi's forces, blowing up many UT-ATs.

A smaller, anti-personnel version, known as the Octuptarra combat tri-droid, served on Coruscant, Utapau, and elsewhere.

Following the execution of the Separatist Council by Darth Sidious's new apprentice, Darth Vader, these units were de-activated.
