e/Head-on engagement

Information
has gloss	eng: A Head-on engagement is one where a surface-to-air missile system or jet aircraft engages another aircraft while the target aircraft is flying towards the attacker. This makes engagement with infra-red homing missiles more difficult because the hot engine exhaust nozzle(s) of the target are pointing away from the attacker. Typically only all-aspect infra-red homing missiles are able perform head-on engagements. Radar-guided missiles are typically able, however head-on many aircraft have a much smaller radar cross-section so the radar may not be able to track/lock onto the target at maximum range in this type of engagement.
