The Pravus ED-3 Oppressor is a fully-automated bipedal combat droid designed and manufactured by Pravus International. The walker was developed to serve as a heavy weapons platform for high-intensity combat operations in urban conditions where heavy firepower would be needed for clearing out large numbers of heavily-armed and protected soldiers and vehicles. Pravus International plans to use them within the Pravus Combat Legions, but also plans to negotiate with national governments for contracts with their military forces for use in war.
