These images of U.S. troops in tight spaces will make you sweat
SUMMARY
A space is confined if it has a limited or restricted entry or exit point.
"Confined spaces include, but are not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork, pipelines, etc.," according to the Occupational Safety and Health Administration.
And the US military trains for all different kinds of scenarios in such spaces.
Here's what they do.
