The SU-76 was developed in the Soviet Union during the Second World War. The intent was for the SU-76 to be a highly mobile tank killer, and it performed well in that role when initially fielded in 1942. Fitted with the powerful ZiS-3 76mm gun the SU-76 was more than a match for most opponents; however, the vehicle's open top and lack of an engine fire wall were generally despised by crews. By the end of the war, newer soviet types such as the SU-100 and better german armor pushed the SU-76 into a new role, that of infantry support. By the end of the war 12,671 had been built.
Following the end of the War the soviets decided to export surplus SU-76M to China and North Korea, where they fought against UN forces. The SU-76M remained in active service with the PLA until the late 1970s when it was finally retired.
The gun in this machine (intelligent design indeed, considering what was available and the time constraints) is the famous ZIS-3, a 76.2 mm gun that even with it's carriage weighed only 1200 pounds! Amazing.
The armor piecing projectile it fired in it's day as the primary anti-tank gun, called the BR-350A, would penetrate two inches of vertical armor at over a mile. PanzerKampfWagen III and IV would not have a chance.
Regarding Waco, tanks punctured the structure at precise locations creating a flue.
The CS/methyl chloride gas was highly flammable and was ignited by incendiaries long denied but ultimately admitted by federals.
Victims attempting to escape were shot. Carlos Ghigliotti developed evidence of 200 shots fired into the structure. Ghigliotti was found dead at his desk dissolving, a serendipitous outcome cheerily pronounced "by natural causes" by none less than the insufferable weasel Gerald Posner, defender of the Foster suicide theory.
The hole blown into the ceiling of the Concrete Room was conical from above, indicating placement of a shaped charge. The blast, radiating debris, overpressure instantly killed 23 women and children.
The only way the federals gained use of military equipment and personnel was through posse comitatus waiver signed by none but the president, said waiver obtained through the conscious lie that drugs were being manufactured. No evidence was ever produced indicating drug manufacture.
Thirty bodies melted when the plug was pulled on the forensic morgue trailer.
The structure was quickly bulldozed and the front door disappeared.
Bill Clinton, Hillary Clinton, Janet Reno gassed, shot, and blew up more civilians in one day than any terrorist group attacking Israelis.
