Military aircrew are practiced at varied approaches, the potential for manpads in the approach climbout funnel are well known,why make it easy?

Curved approaches were not unusual especially when fuel remaining was an issue with just landed aircraft vacating the runway onto the disused runway intersection to enable another fuel short aircraft to land.
