released an updated version of his Convoy script
for Arma 3 on the BI forums
Quote norrin :
These scripts are designed to allow you to set up a simple road convoy that will stay in formation. If the convoy is attacked the foot units will dismount and will engage the attackers. Gunners will remain in their vehicles and will also defend the convoy. There is an option in the script call that allows you to restart the convoy once the encounter is over ie. any remaining units will mount their respective vehicles and continue on their way.
The convoy script is now compatible with the current developer build of ArmA3 (1.05111581). This was an easy one to fix - only one undefined variable I could find in the cam script and just needed to update the class names in the mission.
