In the jungles of Viet Nam this could from 5-30 feet, depending on the density of the vegetation. In the highland forest it could be 15-75 meters and in the open paddies of the Mekong Delta, it could expand to the full effective range of an M-16A1 rifle - 350 meters


Firecracker An artillery round that contains many small bomblets that when fired disperses these in an airburst almost simultaneously. It acquired its name from the sound heard when it goes off.

Forty Percent Rule The average decline in efficiency in accomplishing a complex, impromptu, or unrehearsed mission. It is computed for every person brought into the “need to know” and given a specific task crucial to that mission. Therefore, if the mission requires 10 soldiers to accomplish it the first would be assigned 100% probability the next 60% the next 36% the next 14.4% and so on. Adding all the averages then dividing by the number of participants in this case ten produced the final average. In the above example the possibility of success would be 22.0%. Every rehearsal of the mission increases the probability of success by 50%

FTA F * * k The Army

FUBAR F * * ked Up Beyond All Repair / Recognition

Fulton Recovery System Method of extracting up to 4 people from a hostile area where it was impossible to land either fixed or rotary wing aircraft. A C-130 Blackbird would drop a packet containing a helium tank, a dirigible-shape balloon, the number of extraction suits required and a 900 foot rope. The personnel to be extracted donned their suits and connected a sewn-in hook to one end of the rope. The balloon was inflated, connected to one other end of the rope and sent aloft. When all was in readiness, the C-130 would fly in at approximately 165 kph, hook the line being towed by the balloon. At the moment of extraction the passenger(s) shot straight up in the air approximately 90 feet and accelerated from 0 to 165 kph in less than one minute. The tether was attached to a powerful winch at the rear of the C-130 and the person(s) was winched up into the aircraft. The process can be accomplished by a trained and experienced team in less than 10 minutes.

** Five Star General Rank – equivalent to the European Field Marshall – is only awarded during times of war by the US. Only 5 Army generals where promoted to 5-Star rank while living: General George C. Marshall, General Dwight D. Eisenhower; General Omar Bradley; General Henry H. “Hap” Arnold and General Douglas McArthur. There is no living American 5-Star General. General George Washington was promoted to Five Star rank posthumously.




Ostensibly, being a “people’s army,” the NVA had no rank designation and regulars were only identified as “Cadre.” The NVA, however, soon found that every large organization requires structure to function efficiently and the rank and insignia created more-or-less paralleled that of the Soviet Union’s military.

Initially a sound idea given that the North was heavily infiltrating the South with regulars in 1964-65.
