Time as Ordnance

In 1945 the US War Department published a manual on how to service a watch. TM 9-1575 is the document this section is named for, and the reason.

Mid-war, the US Army published a depot-level manual on maintaining watches and clocks. TM 9-1575 is why this section carries the name: a watch in service is ordnance, maintained like a weapon, because the time it keeps is part of the fight.
