I think strafing has something to do with combat aircraft (a strafing run, probably fly by shooting?), but where I know it from, is early shooters (haven’t played any in over a decade, not sure if that word is still used), strafing was moving sideways.

edit: my guess for the actual meaning was close-ish:

> Strafing is the military practice of attacking ground targets from low-flying aircraft using aircraft-mounted automatic weapons

> The word is an adaptation of German strafen, to punish, specifically from the humorous adaptation of the German anti-British slogan Gott strafe England (May God punish England), dating back to World War I.
