Talk:List of Urcean armored vehicles

SAV-5
The SAV-5, officially designated the '''Standard Armored Vehicle, Mk. 5''', was a Urcean light tank designed and used during the early Great War. Though it was not the first tank in use by the Royal and Imperial Army, it was the first produced in large numbers and it was the first tank of native design. The SAV-5 was the main tank used in dedicated armored divisions of the Royal and Imperial Army. It was primarily designed based on observations of trench warfare in eastern Burgundie in the first two years of the Great War. The mass production and deployment of the SAV-5 allowed for the Royal and Imperial Army to end the stalemate in the Kingdom of Dericania in the period 1930-1933, ending the two years of trench warfare and demonstrating the value of armored warfare to the Levantine powers. It was largely obsolete by the late 1930s, but the focus on Urcean medium tank development - which produced the SAV-6, Urcea's first medium tank - allowed updated versions of the SAV-5 to remain in service until 1940, when it was supplanted by the SAV-7.

History
The early phase of the Great War included an invasion of eastern Burgundie by Derian nationalists in 1927 which was stopped by layers of trenches buttressed with interlocking fire from machine guns. This new defense tactic stopped the nearly entirely infantry-based nationalist Legion. Artillery barrages proved unable to break the trenches, and Derian forces soon emulated them, leading to opposing networks of trenches. Observers from the Royal and Imperial Army hypothesized that a heavily armored vehicle used in a massed advance could break the lines. While Urcea has several models of licensed armored vehicles and tanks from overseas, none of them were satisfactory for use against Derian trenches. Consequently, the Army provided specifications for a new armored vehicle and began a design competition to provide the best new domestic-designed tank for use in Dericania. The design that would become the SAV-5 won the competition and subsequently began production in 1929. SAV-5's were instrumental in the Royal and Imperial Army's advances in 1931, executing a flanking operation around Corcra, restoring the Imperial capital to Urcean control. The tanks suffered a number of design problems relating to its reliability, and most deployed units suffered major breakdowns in 1931-1932 during the wet season in Dericania. The SAV-5 was evalutated by the Yonderian Armed Forces in early 1933 but was ultimately turned down in favor of the AMG-34. The SAV-5 remained Urcea's primary armored vehicle through 1937, when it was gradually phased out or sent for duty in the Audonian theater of the Great War. Military advisers and reconnaissance in Sarpedon through 1935 revealed the need for a heavier, better-armed tank, as the Imperial Legion already had tanks similar to the the SAV-5. As the Royal and Imperial Army deployed to Sarpedon in 1938, it retained a number of SAV-5's to fill the need for armor until more SAV-6 units were delivered. The SAV-5 continued to serve admirably as a light infantry support tank in Veltorina, but its design shortfalls and reliability issues remained consistent. SAV-5's were gradually taken off the front and replaced with the SAV-7 by 1940.

SAV-6
The SAV-6, officially designated the '''Standard Armored Vehicle, Mk. 6''', was a Urcean medium tank in use during the Great War. Urcea's first medium tank, it was designed to fight other armored fighting vehicles in support of infantry units. The SAV-6 was designed with observations of Imperial Legion armor in mind, and the SAV-6 was effective in its earliest years of deployment of countering and destroying Caphirian light tanks used in support of infantry. Beginning in 1940, the SAV-6 eventually saw use as a breakthrough cruiser tank effectively during LOTA counter-attacks in Veltorina. The SAV-6's competitive edge had been lost by late 1941, and the SAV-9 was designed to replace all Urcean tanks and become the standard armored unit. The SAV-6 remained in service in all theaters until May of 1945, after which time it was relegated to the Audonian theater for infantry support. Considered a pioneering and reliable design, the SAV-6 is consistently rated by historians as one of the best tanks of the Great War.

SAV-9
The SAV-9, officially designated the '''Standard Armored Vehicle, Mk. 9''', was a Urcean medium tank primarily in use during the Great War. During the last years of the war and following the war, Urcea sold many of its units to Yonderre, where it would remain in service as the CdC mle 1948 for several years and prove influential in Yonderian armor design in the following years.

History
Based on the experience of the Northern Sarpedon theater of the war, Urcean military designers scrambled to develop a new, general-purpose medium tank to counter the powerful armored vehicles employed by Caphiria's Imperial Legion. The SAV-9, as designed, was intended to replace the SAV-6, SAV-8, and any tank destroyers with a standardized, heavily-armored tank with a 75mm gun. Originally intended to be a new variant of the SAV-6, the SAV-9 took on an entirely new chassis and design by its final outline in 1940. Featuring even more sloped armor than its predecessors and a heavier gun than any medium or light tank employed by Urcea through that point, the SAV-9 was considerably more advanced than its predecessors and most contemporaries. After years of problems with prototypes, the first production models were introduced to the Sarpedon front in May of 1942, but these models saw various problems with reliability and questionable design choices including crew escape hatches and line of sight for tank commanders. These problems kept the SAV-9's predecessors in the field until 1945, when the SAV-9's problems were remedied with upgraded models, which included higher speeds. The SAV-9 became the tank of choice for the Royal and Imperial Army during the late 1940s, and the higher speeds of later models allowed the SAV-9 to replace light tanks, such as the SAV-7, in maneuver roles. Many historians have called the SAV-9 the first (or prototype) main battle tank given its universal functionality. The lessons of its universal applications lead to the design of its successor, the SAV-10, which began service in 1948.

In Yonderian service
The Army Procurement Command of Yonderre had long sought a replacement for its aging fleet of Somua cavalry tanks. Four SAV-9 tanks were bought for testing in 1947. Most impressed by the SAV-9's performance, the tank was greenlit for service as the Char de Combat modéle 1948 and the Army Procurement Command put in an order for additional vehicles. The first battalion of the Guard Cuirassier Division was the first Yonderian unit to be equipped with CdC mle 1948s, the battalion reaching full complement by late 1949. The tankers responded very favourably to their news vehicles, citing the increased armour protection, weapons capability and speed as great improvements.

The CdC mle 1948 served as the main battle tank of the Yonderian armoured divisions until its eventual replacement by the AMY-58, although it was not until 1965 that it was fully replaced. It served alongside the AMY-13t and AMY-25t light tanks, whose designs both drew on that of the SAV-9. The CdC mle 1948 was well-liked by its crews, though it was known to suffer from transmission failures and required frequent maintenance, even more so than in its Urcean career due to its advanced age. By the time it was withdrawn from Yonderian service, more than 20% of Yonderre's fleet of CdC mle 1948s had been scrapped and scavenged for spare parts.

SIAV-4
The SIAV-4, officially designated the '''Standard Infantry Armored Vehicle, Mk. 4''', was a half track armored personnel carrier designed and used by Urcea during the Great War.
