However, I did take part in free fire zones and I did take part in harassment interdiction fire.

Question to you combat vets about the term "interdiction fire":

I always thought interdiction fire was done by a weapons system capable of indirect fire, ie. artillery, aircraft, etc., the idea being to deny the enemy the ability to move men & supplies through a given area. If I am right, just how is this done with the weapons that Lt. Kerry had available to him on his Swift Boat? His heaviest weapon was a twin .50 (which is a direct fire weapon) or possible a grenade launcher (rather short range for interdiction fire). Just wondering what he might have meant since Sen. Kerry considered that activity a "war crime" until fairly recently.

As I understand it, 25th Division ROE, a free fire zone was an area where you did not need permission to return fire when fired up on. Harassment and Interdiction fire was that which placed areas of likely enemy activity in a Free Fire zone under fire, artillery mostly.

A Free Fire zone was Indian Territory, such as War Zone C and D for example. This BS about Free fire zones galls my kybes, if it was enemy controlled, as defined by the RVN Provence Chief and US LNO it was free fire if not you had to ask permission to return fire.
