[Source] Sequencer charges were a weapon used during the Galactic Civil War. They had two settings: automatic and manual. The automatic setting worked like a land mine, while manual worked like a detonation pack. Kyle Katarn demonstrated the sequencer charge's destructive capability when he destroyed the Imperial mining facility on Gromas 16, as well as the dark trooper weapons lab on Anteevy and the Arc Hammer itself. The Dark Jedi Jerec was also known for equipping his troops with them.
