You're offline. Tools marked Saved open without a signal; the others need a connection.
Use without a signal
Publications, iPhone and offline computers
Save every tool on this device before you go somewhere with no signal, like the motor pool or the field. Saved tools update themselves the next time you open them with a signal.
iPhone and iPad: add this page to the Home Screen first (Share, then Add to Home Screen), open it from there and save. Safari clears saved sites that go unused for about a week; Home Screen apps keep them.
A computer that never gets a signal? Download the Offline Package: every tool in a folder that opens with no connection or install.

Read before use
Unclassified Tools is an unofficial landing page for personal projects. It and the tools it lists are not affiliated with, endorsed by, or a replacement for any U.S. Army or Department of Defense site, portal, course, publication or program, and none of them trains, tests, certifies or records anything.
Every tool is built only from material approved for public release. The publications govern; standards change between editions. Where a tool and current doctrine, your unit or your chain of command differ, follow them. Each tool keeps its own notice: read it before use.
Units, callsigns, grids, names and other example data in the tools are notional.
Never enter classified, CUI or personal information in any tool or problem report; reports are public. This page keeps a copy of itself for offline use and remembers only your theme, in this browser; it sends nothing anywhere.
