What is the insignia for a Brigadier General in the Marine Corps?

The insignia for a Brigadier General in the Marine Corps is represented by one silver star. This design element signifies the rank and is consistent across the branches of the U.S. Armed Forces, where a silver star denotes the rank of Brigadier General.
