Right now, tank crews train in one box, helicopter pilots train in another, infantry soldiers train somewhere else entirely, and almost none of these systems talk to each other. STE is supposed to fix that: a single, connected environment where a platoon can rehearse a mission, a commander can wargame a course of action, and a logistics officer can practice convoy operations, all inside the same synthetic world at the same time.

On paper, that vision is genuinely compelling. In practice, the program has spent most of its life since its 2017 launch renegotiating what
