VICE does it right, as usual:
The two part documentary follows a group of war vets and history buffs who like to realistically reenact the Vietnam War.
They are obviously using blanks, but I wonder how controlled the inspection of ammunition and firearms is? Hopefully better than it looks. Also, some of that shooting looked quite close range considering blanks have killed people in the past.
Well, using airsoft replicas instead firing blanks eliminate “GI Effect”. Historic and reenactment settings airsoft games are quite popular in some countries.
