Death Watch portable shield

Around 20 BBY, during the battle of Sundari, renegade Death Watch members, mostly formed from the branch of Death Watch, the Nite Owls used a portable shield to protect themselves from Mandalorian super commandos.

History
After Darth Maul executed Duchess Satine Kryze on Mandalore in the Sundari Royal Palace, he imprisoned Jedi Master Obi-Wan Kenobi. Kenobi was rescued by the renegade members of Death Watch, and they started to escape from the Mandalorian super commandos, who were loyal to Darth Maul. After a firefight arose, several members of Death Watch activated the portable shields, in order to gain protection from the arm blasters of the commandos.
