Man, I hate it when people like robertfenix use words, assuming they know what they mean, when they really don't.

Merriam-Webster Online

2 : a thrust-transmitting carrier that positions a missile in a gun barrel or launching tube and that prevents the escape of gas ahead of the missile

MS Encarta

2. support for projectile in weapon: a sleeve placed around a projectile so that it can be fired from a weapon with a larger bore. The sabot drops away shortly after the projectile is fired.

Infoplease Dictionary

b. a soft metal ring at the base of a projectile that makes the projectile conform to the rifling grooves of a gun

Onelook Dictionary (Just to be annoyingly redundant...)

2. (n.) A thick, circular disk of wood, to which the cartridge bag and projectile are attached, in fixed ammunition for cannon; also, a piece of soft metal attached to a projectile to take the groove of the rifling.

RPG=NO BARREL; NO BARREL=NO SABOT

Sabot is NOT a round. Sabot is NOT incindiary. Sabot will NEVER pierce armor.

An RPG has not, does not, and will NEVER fire a sabot round. For the love of GOD, the round of and RPG never even sees the inside of the LAUNCH TUBE!

Communication is not just the use of officially recognized words, but convying a point of view or infomation.

Reguardless of if you like it or not his description is accurate.

Shaped charge employs explosive to collapse a metalic or glass liner material to follow the axis of the direction that the explosive vents. THis forms into an exceptionally long rod [on the order of ~ 100:1 lenght to diameter]. It is also solid , however since it is under massive pressure it behaves like a liquid and flows.

Like wize when this massive pressure stretching rod strikes the armor it too acts like a fluid and flows.

Thus ballistic researchers study both APFSDS and shaped charge jets as long rods at velocity ranging from 1000-8000m/s. Similarly resistance to such penetration is studied in the same manner except , while the APFSDS has considerable strength, the jet does not [which is why its easy to deform in the first place].

Ergo his description, while novel is correct.

"robertfenix" A suggestion, replace the word "sabot" with "mechanically weak rod" in your description. Then he won't understand what you are say , but it will be more accurate.

Oh and a final note, here is what the Army had to say about it, here is an excerpt

One armor expert at Fort Knox, Ky., suggested the tank may have been hit by an updated RPG. About 15 years ago, Russian scientists created tandem-warhead anti-tank-grenades designed to defeat reactive armor. The new round, a PG-7VR, can be fired from an RPG-7V launcher and might have left the unusual signature on the tank.

In addition, the Russians have developed an improved weapon, the RPG-22. These and perhaps even newer variants have been used against American forces in Afghanistan. It is believed U.S. troops seized some that have been returned to the United States for testing, but scant details about their effects and “fingerprints” are available.

Still another possibility is a retrofitted warhead for the RPG system being developed by a Swiss manufacturer.

At this time, it appears most likely that an RPG-22 or some other improved variant of the Russian-designed weapon damaged the M1 tank, sources concluded. The damage certainly was caused by some sort of shaped-charge or hollow-charge warhead, and the cohesive nature of the destructive jet suggests a more effective weapon than a fragmented-jet RPG-7.

A spokesman for General Dynamics Land Systems, which manufactures the Abrams, said company engineers agree some type of RPG probably caused the damage. After checking with them, the spokesman delivered the manufacturer’s verdict: The tank was hit by “a ‘golden’ RPG” — an extremely lucky shot.

In the end, a civilian weapons expert said, “I hope it was a lucky shot and we are not part of someone’s test program. Being a live target is no fun.”

John Roos is editor of Armed Forces Journal, which is owned by Army Times Publishing Co.

Notice how the ARMY expert says it was possibly a PG-7VR round.

Delta Chaos, next time, try not to question the facts.
