Wear on a range is wear on readiness
Every round fired is load on the containment. Backstops erode, baffles fatigue, structures absorb hits they were built for but not forever. Logged as ordinary upkeep, that wear slides down the priority list until a failed inspection or a safety stand-down pulls the range offline, and the training calendar goes with it.
Build and maintain to the round count
Durable range construction is specified to what it actually absorbs, not to a generic service life. Containment sized to the real round count, and maintained on that basis, keeps a range open and a unit training on schedule.
Keeping a range in service starts with range and containment built for sustained live fire.
