milk run

What does milk run mean?

A routine, low-risk sortie against an easy or familiar target. Said with cheerful sarcasm — because every veteran knew a milk run could turn into a bloodbath the moment the flak got lucky.

"Briefing called it a milk run. We lost two crews."

Origin

RAF and USAAF, WWII. From the daily milk delivery — a known route, same stops, no surprises. Aircrew used it for sorties so familiar and unopposed they were as predictable as the milkman.
