An improvement program will eventually upgrade all M1A1 tanks with steel encased depleted uranium armor, which has a density at least two-and-a-half times greater than steel. The depleted uranium armor will raise the total weight of the Abrams tank to 65 tons, but offers vastly improved protection in the bargain. The stowage for the main armament ammunition is in armored ammunition boxes behind sliding armor doors. Armor bulkheads separate the crew compartment from the fuel tanks. The tank is equipped with an automatic Halon fire extinguishing system. This system automatically activates within 2 milliseconds of either a flash or a fire within the various compartments of the vehicle. The top panels of the tank are designed to blow outwards in the event of penetration by a HEAT projectile. Nuclear, Biological and Chemical (NBC) warfare protection is provided by an overpressure clean-air conditioning air system, a radiological warning system, and a chemical agent detector. The crew are individually equipped with protective suits and masks. The Marine Corps has fielded the M1A1 Common Tank to replace the aging M60A1 Rise/Passive tank. The M60 has reached the end of its service life and lacks the capability to survive and to defeat the threats expected to be encountered on the modern battlefield. During Operation Desert Shield/Storm, the Marine Corps borrowed 60 M1A1s (called the M1A1 Heavy Armor) from the US Army. There were also 16 Marine Corps M1A1 Tanks delivered on an accelerated schedule for employment during the operation. This total of 76 M1A1 tanks was employed by 2d Tank Battalion and elements of 4th Tank Battalion. The M1A1 tanks saw immediate action during the I Marine Expeditionary Force (IMEF) drive through the burning Kuwaiti oil fields. All loaned tanks were returned to the US Army after Desert Storm. Due to unique Marine Corps amphibious requirements, and the need for both supportability and interoperability between the Marine Corps and the US Army, the two services agreed to jointly produce the M1A1 Main Battle Tank. The M1A1 MBT has the capability to conduct operations ashore. It is compatible with all US Navy amphibious ships and craft (to include the LCAC) and Maritime Prepositioning Ships (MPS). The USMC completed fielding of all tanks, to include active, reserve, MPS, and depot maintenance float (DMF) during FY 96. In 1995 the 26th MEU became the first amphibiously deployed unit to carry the M1A1. This added some complication to the logistics of the unit due to the tank's weight. Topping the scales at over 68 tons the vehicle requires special care during amphibious operations. One tank can be carried at a time on an Air Cushioned Landing Craft (LCAC), two on a Landing Craft Utility (LCU), but only during fairly calm seas. For operations with the Marine Corps, tanks have been equipped with special fording systems. These modifications include extended air intake and exhaust tubes that allow the vehicles to cross rivers and shallow waters such as the surf zones that Marines operate in.
When the Allied armies landed on the Normandy beaches on 6 June 1944 the backbone of the armoured reaction force awaiting them was made up of 758 Pzkpfw IV tanks, a number which represents almost half the fully-tracked vehicles available for the defence of the West. The first models of these tanks had entered service in November 1937 and although replacements had been considered, the original design was continually up-gunned and up-armoured. Perhaps lacking the glamour of the Panther and Tiger, the most recent variant, the Pzkpfw IV ausf H, was at least the equal of the best British and American tanks. Drawing on official documentation and unit histories Dennis Oliver investigates the formations that operated these deservedly famous vehicles and uses archive photos and extensively researched colour illustrations to examine the markings, camouflage and technical aspects of the Pzkpfw IV tanks that served on the Western Front during the critical summer of 1944. A key section of his book displays available model kits and aftermarket products, complemented by a gallery of beautifully constructed and painted models in various scales. Technical details as well as modifications introduced during production and in the field are also examined, providing everything the modeller needs to recreate an accurate representation of these historic vehicles.
Most diesel Sherman tanks were sent Lend-Lease to the Soviet union for fuel compatibility with other Soviet tanksThese also had mostly all steel tracks reasoning probably less paved roads in the Eastern front that would be destroyed and steel longer lasting in extreme conditions. Also maybe steel better on ice?
Bill, They found most of the welding time spend building welded hull M4 tanks was done putting the front plate together, casting the whole hull from Molten Steel was of course quicker and more cost effective, but not all the Sherman factories had the steel casting facilities that could handle huge castings like that. The Composite Hull M4 Sherman was a compromise, the front hull was made from a large casting, the rest was welded together like a normal welded hull version. This saved the welding time, and the smaller casting for the front hull was easier to produce than a full hull casting.
This is an M4 composite hull, notice how the front is curved and this was the cast part, made by pouring molting steel into a big mold, but the rest of the tank is just like a normal welded hull M4.
It could have also been like this Sherman a large hatch M4A3 75W tank.This model of the Sherman solved the welding problem in an even easier way, they just made the whole front plate from one rolled steel plate. This redesign also resulted in bigger hatches for the driver and co-driver.
But they also had a M4A3E8 hull mount the T26 turret with the 90mm and they tested it for at least 2000 miles. They went as far as to weigh the tank up to 102,000 lbs for that. They were looking at a possible replacement for the jumbo at the time.
Narrator: Mao knew his military was far inferior to the American's in tanks, artillery and airpower. But he had taken the measure of MacArthur, and discerned a weakness. In early November, Mao sent small cadres of troops to attack all along the approaching American front. Then his men pulled back in what looked like a full retreat.
I agree it may sound frustrating but in all honesty it would be belligerent to intentionally utilize their VPN service to break the law. I think they may have mistakenly advised some consumers that torrenting digital content which was illegal from within that country or region was grounds for TorGuard breaking the law. This is a similar incident with MegaUpload was targeted for hosting pirated content from which they claimed they had no transparency over. 2b1af7f3a8
