sustainment

Definition

Military jargon for keeping troops fed, armed, and operational in the field—basically the logistics of not letting your army fall apart. It encompasses everything from ammunition resupply to field hospitals to making sure soldiers have boots. The unglamorous but absolutely critical business of keeping the war machine running.

Example Usage

The battalion's sustainment operations required a constant flow of supply convoys bringing food, fuel, and ammunition to forward operating bases.

ballistic

Technically refers to projectiles moving under their own momentum, gravity, and air resistance after launch—the physics of things that go up and must come down.
