Skink Anti-aircraft Tank
Tank AA, 20 mm Quad, Skink was a Canadian self-propelled anti-aircraft gun, developed in 1943–44, in response to a requirement from the First Canadian Army. Due to a lack of threat from the German , the Skink was cancelled in 1944 after only three were built from Grizzly I cruisers. Development The development of a fully enclosed quadruple 20 mm mounting on the chassis of the Grizzly tank (M4A1 Sherman tanks built in Canada from August 1943) was approved by the Canadian Army Technical Development Board as Project 47 in March, 1943. In keeping with the tradition of giving Canadian armoured fighting vehicles animal names, the proposed tank was named after the skink, Ontario's only lizard. The Canadian Ministry of Munitions and Supply had the turret designed in-house by its Army Engineering Design Branch (AEDB) with help from the Inspection Board. The Waterloo Manufacturing Co. in Waterloo, Ontario, was given the task of building a preliminary wooden mock-up. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacis
A glacis (, ) in military engineering is an artificial slope as part of a medieval castle or in early modern fortresses. They may be constructed of earth as a temporary structure or of stone in more permanent structure. More generally, a glacis is any slope, natural or artificial, which fulfils the above requirements. The etymology of this French word suggests a slope made dangerous with ice, hence the relationship with ''glacier''. A ''glacis plate'' is the sloped front-most section of the hull of a tank or other armoured fighting vehicle. Ancient fortifications A glacis could also appear in ancient fortresses, such as the one the ancient Egyptians built at Semna in Nubia. Here it was used by them to prevent enemy siege engines from weakening defensive walls. Hillforts in Britain started to incorporate glacis around 350 BC. Those at Maiden Castle, Dorset were high. Medieval fortifications Glacises, also called taluses, were incorporated into medieval fortifications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waterloo is a city in the Canadian province of Ontario. It is one of three cities in the Regional Municipality of Waterloo (formerly Waterloo County, Ontario, Waterloo County). Waterloo is situated about west-southwest of Toronto, but it is not considered to be part of the Greater Toronto Area (GTA). Due to the close proximity of the city of Kitchener, Ontario, Kitchener to Waterloo, the two together are often referred to as "Kitchener–Waterloo", "K-W", or "The Twin Cities". While several unsuccessful attempts to combine the municipalities of Kitchener and Waterloo have been made, following the 1973 establishment of the Region of Waterloo, less motivation to do so existed, and as a result, Waterloo remains an independent city.

Semovente Da 20/70 Quadruplo
The Semovente da 20/70 quadruplo was an experimental self-propelled anti-aircraft weapon developed for the Royal Italian Army, Italian Royal Army during World War II. Development During 1942 the Royal Italian Army had ordered the development of a self-propelled anti-aircraft weapon to be used in the North African Campaign, North African theatre of operations and provide protection to mechanised columns, which were often the target of the Royal Air Force (RAF), without credible air defence. To save time and materials, the hull of the M15/42 tank was used as the basis for the quadruplo: The original turret was removed and replaced with a polygonal welded open turret, containing quadruple Cannone-Mitragliera da 20/77 (Scotti), 20 mm-Scotti Isotta Fraschini 20/70 guns, with -5° to + 90° elevation; the autocannon had been specially modified so they could use disintegrating link belt ammunition resulting in an increased rate of fire 600 rounds per minute per gun.

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebach M ...
