No guesswork, no flipping through a binder. Just the right checks, in the right order, for your equipment.
Item Numbers, procedures, and not-mission-capable criteria reproduced verbatim from the equipment's Technical Manual, shown right alongside plain-English steps.
Numbered, tappable steps with engine and setup-state banners and built-in safety warnings — with troubleshooting before you ever mark a fault.
Auto-fills Item Numbers, status symbols, and NMC fault criteria so you can transcribe a clean fault list straight onto your unit's DA Form 5988-E.
HMMWV, LMTV, and the MEP-831A/832A tactical quiet generator — each backed by its open-source operator's Technical Manual.
Works entirely offline. Your sessions, operator info, and vehicle profiles stay on your device — nothing is ever uploaded to a server.

The MEP-831A/832A generator set — setup-state aware checks with the right safety warnings.
