Minefields could narrow the approaches to Reach and bring attackers into the orbital platforms' fields of fire. The Covenant's ability to jump within the system complicates that plan, since it can bypass predictable entry points. Reach's existing nuclear minefield is acknowledged, but the proposed alternative uses several fields around likely approaches and concealed arrival positions. Different mine types and supporting fire would make sweeping harder. Mines and gun positions need to work together, just as barbed wire supports defended ground positions.

Using mines to support orbital defenses
Minefields around Reach need to work with orbital guns to channel attackers and resist sweeping.
