Range 400

What you're looking at is a picture of Range 400 in 29 Palms, California. This range is designed to be a culminating event for a company-sized element.

If you look closely at the bottom of the picture, you'll see Charlie Company moving through the draw towards the objective. The smoke is where the impacts of indirect fire (mortars) are landing as the Marines close with the enemy.

This range is EXTREMELY intense with mortars landing, overhead machine gun fire, and explosives breaches going off. Hopefully, you get some feeling of this through the photo.
