Practical instruction is also found in readily purchased U. S. Army manuals, including three from the Vietnam War: Boobytraps, Explosives and Demolitions, and the Improvised Munitions Handbook. Page 69 of Boobytraps contains a drawing of about twenty people standing outside a three-story building. Smoke pours from windows. Several women, apparently civilians, are among the bystanders. An undetonated bomb is represented in the foreground by a box bearing the word explosive. The text reads: “A double delay chain detonating boobytrap should be very effective if timed right and skillfully laid. First, there is the explosive of a minor charge laid in an upper story damaging the building only slightly. Then, after a curious crowd has gathered, a second heavy charge or series of charges go off, seriously damaging or destroying the building and killing or wounding many onlookers.” This is forthright instruction in terrorism, published by the government of the United States.
