October 8, 2006: The Russian T-72 tank is the most widely used tank ever. Over 50,000 have been built. More than any model in World War II. Ironically, the T-72 was a stopgap design, intended to provide a replacement for the more advanced T-64, which was not successful. Production began in 1972, and the T-72 entered service in 1976. Compared to the earlier T-62 and T-64, the T-72 was successful. It was reliable, or so it was thought. But in 1982, Syrian T-72s went up against Israeli Merkavas. The Syrians lost badly. In 1991, Iraqi T-72s were helpless against American M-1 tanks, and M-2 Infantry Fighting Vehicles. But the T-72 remained popular. Partly because it was so cheap. Cold War surplus vehicles, in good shape, could be had for as little as $100,000. The vehicle was still popular because of its reliability. Most nations never expected to use their T-72s in combat, but it was more useful for them to be in running condition in peacetime, when they could control unruly civilians.
Another reason for the popularity of the T-72 is the large number of upgrades available. While the basic T72 was pretty unimpressive, a few upgrades could turn it into a much more formidable (and expensive) tank. For example, modern, computerized, fire control systems, with laser range finders and night-vision sights, and quality ammunition, transforms a T-72 into a very lethal system. While such a tank would still get blasted by an M-1, if the T-72 spotted the M-1 first, and got a flank shot, it could win. The T-72 is also a very mobile vehicle, about on a par with the famously nimble M-1. But protection is always going to be a problem. The stock T-72 is a 41 ton vehicle that is 23 feet long, 11 feet wide and 7.5 feet high. An M-1 is 62 tons, 32 feet long, 12 feet wide and eight feet high. The extra weight is mostly armor, and from the front, the M-1 is still very difficult to kill. To survive, a T-72 not only needs to accessorize, but requires a well trained crew. Most nations using T-72s, don't like to invest in crew training. But that's what makes the most difference in combat.
The T-72 is surviving into the 21st century because Russia's new T-90 was, again, a fall-back design. The T-80 was supposed to be the successor to the T-72. But like the T-62 and T-64 before it, the T-80 didn't quite work out as planned. So the T-72, with a much improved turret and all manner of gadgets, was trotted out as the T-90. At 47 tons, but it's still 23 feet long, 11 feet wide and 7.5 feet high. Same package, better contents. And with well trained crews, it could be deadly.
