Jenn Smeel was a captain of Human descent within the Royal Naboo Security Forces. He served during the concluding years of the Galactic Republic.
During the Trade Federation's invasion of Naboo in 32 BBY, Smeel was a resident of the planet. Subsequently, he became a member of Queen Padmé Amidala's company, journeying to the Gungan Sacred Place to forge an alliance with Boss Nass to combat the invading forces. The conflict reached its conclusion when the combined forces of the Naboo people and the Gungan Grand Army triumphed over the Trade Federation.
After the declaration of the New Order, Smeel enlisted in the Galactic Empire. There, he achieved the rank of colonel within the Imperial Army. Following Crix Madine's defection to the Rebel Alliance during the Galactic Civil War, Jenn functioned as a commanding officer for the storm commandos.
