SibeiSuayKia,
The scenario you present is a standard one in POI missions
(Protection of Installations). There is already an SOP to handle
this.
If the situation is relatively benign like the one you describe,
the car will be aimed at, challenged and ordered to stop over a
megaphone. If the car refuses to stop after two or three
challenges, it is threatened with deadly force ("Stop!" "Stop!"
"Stop or I will shoot!"). If it still refuses to stop, it is
attacked with the minimum force needed to stop it. Assuming all of
these rules are followed, even if the car turns out to be full of
unarmed civilians, you have broken no laws. This is similar to how
police handle the situation.
If the situation is more dangerous (e.g. the car starts moving
suddenly when you approach within 50m), and the commander on the
ground has reason to believe he is under attack (e.g. bombings have
occured before), you are allowed to open fire immediately without a
challenge. Again, minimum force must be used. This is not against
military law even if you are shown later to be in error, but you
must demonstrate that you had reasonable cause to think you were in
danger and that you used minimum force.
The same situation applies to a civilian that has gotten out of the
car, or approaches troops or a checkpoint. Target, challenge and if
necessary engage with minimum force. If you are in danger, defend
yourself with minimum force.
There are also SOPs for searching suspect vehicles. The basic idea
is that you get the occupants of the vehicle to open everything
while you look and ask questions at a safe distance. For searching
civilians in time of war, the same thing applies (make him pull up
his shirt, drop his pants and open his bags for inspection at a
safe distance). For searching of females, female troops or
policewomen and a private search area should be arranged (now you
know why we have female troops).
Go ask soldiers from the new POI batallion 6SIR -- they will give
you the full story.
