investigating UN Pilot final mission

[Comrade14]

After destroying the enemy convoy I'm told to continue patrolling the road, how long am I supposed to patrol for? I flew around for about 10 minutes with no updates or anything. All enemy infantry are dead as well besides the two invincible ones in the treeline. What am I supposed to do?

Check this play though of the last mission and see if it helps, if not let me know and I can see if maybe there is a bug.

Thanks.
