Many Jawas were killed by stormtroopers searching for R2-D2. They used banthas and gaffi sticks to feign a Tusken Raider attack, but Obi-Wan saw through the ruse.
If two or more Stormtroopers are present where the opponent has Jawas, target as many Jawas there as desired. Draw destiny. If destiny > the number of Jawas you targeted, they are immediately lost.
