Essential Carry Skills (ECS) is as its name implies, are the necessary skills needed to successfully carry a concealed firearm, deploy the firearm under physical and mental stress.
ECS 3 continues to build on the combative skills learned in the previous classes, and introduces the use of flash light use, weapons mounted lights (wpl), and movement. Both simulator and live fire exercises in low light environments are the mainstay for cementing the principles behind these skills.
