Vanguard Squadron was a New Republic starfighter squadron that was active during the Galactic Civil War and was based on the Acclamator-class assault ship Lodestar, the flagship of General Hera Syndulla‘s battle group, some weeks after the Battle of Endor in 4 ABY. The squadron fought at the planet Argai Minor and was later present at the Pandem Nai system during the attack on the Galactic Empire‘s 204th Imperial Fighter Wing at the planet Pandem Nai.

Around 5 ABY, Vanguard Squadron went on a mission to the Bormea sector, with Syndulla going to aid them part way in. However, after the general’s battle group was devastated by the 204th in the Cerberon system, Syndulla and Vanguard Squadron traveled to the star system to assist the remaining forces. The squadron lost at least two fighters, and it helped pursue the 204th, which escaped aboard the bulk freighter Yadeez.
