The main reason the military conducts confined space training is for rescues, oftentimes a fellow service member who may become trapped while doing some kind of maintenance.
Such as a fellow airman working on an aircraft.
Sometimes they have to be tethered into the confined space.
Military firefighter units often train for such confined space scenarios.
Service members even train in building collapse simulators.
Or for hazmat situations.
This variety of confined spaces training scenarios give troops experience in how to read site maps and determine what kind of equipment and procedures to use.
But first they have to get used to the confined spaces.
And the whole thing seems pretty grueling.
