Secure destruction, in-place.
eMACS is a trailer-mounted closed chamber that destroys ordnance on the owner's site using two-stage combustion. Custody stays inside the perimeter. In service since 2001.

eMACS
The alternatives
Open burning and detonation run with no containment or emissions control. The EPA has proposed tighter standards (89 FR 19952).
Live ammunition travels public roads to a permitted depot. Every transfer is a custody break and every escort is a cost.
Centralised and permitted over months to years. They cannot reach ordnance that is distributed across bases and agencies.
A closed chamber that reaches the site in days. Material never leaves the owner's perimeter.
Chain of custody
Every step is logged to one timestamped record per item.
One record, two uses
The record that certifies each item's destruction is also the verified label the detection model is built to train on.
