Today we present an article from the January-February 1986 issue of ARMOR magazine titled “Trunnions on the Move” by Robin Fletcher. Although thirty years old, this article is still relevant for those with an interest in tank layout design, particularly issues involved in turret design. With the end of the Cold War, much of the impetus to produce new MBTs using some of the alternative turret ideas explored in this article was lost. However, the introduction of the new Russian Armata will no doubt reignite interest in some of these turret and gun mounting concepts. We have posted the pages of the article in a photo gallery below, or the entire issue can be downloaded as a PDF here.
