Were the warnings issued by same plane that shot it down? Was there a shoot-down order given before any attempt to escort away?
Friendly fire...”Sorry, my mistake.”
Standard is radio calls on Guard to warn.
In war zone approaching a fighter one does not rejoin off the wing and “escort”
Warn, then shoot. . .especially if violating sovereign airspace.
Do not confuse with intercepts we have with Russian bombers lumbering along in the ADIZ. Entirely different.
