Definition

Fragmentary Order—a quick modification to existing operation orders that changes specific details without rewriting the entire plan. For when your carefully crafted strategy meets reality's complete indifference.

Example Usage

We just received a FRAGO moving our jump-off time up by two hours—pass it down to the squad leaders.

Origin

Abbreviated from 'fragmentary order,' standard military planning terminology formalized mid-20th century

Fun Fact

Some operations generate so many FRAGOs that troops joke they're making up the plan as they go—which is often uncomfortably accurate.
