Shooting the truck on approach to the roadblock is acceptable. Shooting the guy outside the pickup with no visible weapon instead of attempting to detain him would have gotten you in trouble.
Firing on the stopped truck without first ordering the people out of it would have gotten you in trouble.
There were no visible weapons and no clear threat once the truck was forced to stop, under ROE you would be facing a possible court martial for these actions.
