From the Vault: Chieftain Articles and Documents

Today we present our most substantial “From the Vault” post yet, consisting of several articles and archival documents pertaining to the British cold war era Chieftain MBT.

First we have a three page article about the Chieftain from the Jan-Feb 1970 issues of ARMOR written by Staff Sergeant Edmund L. Devereaux III.  The author of the article is a US tanker and is writing out his first hand experience with the then new Chieftain tank during a training exercise with the British.


Next up is an article from International Defense Review from 1970 titled “Chieftain-Main Battle tank for the 1970s.”


Next is a 1976 IDR article titled “The Combat-Improved Chieftain – First Impressions” by Geneva F. Schreier.


Our final IDR article is one from 1976 titled “Improved Chieftain for Iran.”  This piece describes the improved Chieftain offered to Iran and dubbed the Shir Iran meaning Lion of Iran in Farsi.  This vehicle would lay the groundwork for the later Challenger I tank accepted by the British Army in the 1980’s.

    I would like to know if I am correct in thinking that for the early marks of Chieftain the auxillary gunner’s sight was mounted just to the right of the main gun in a deep recess in the armour? I am making a Takon Mk2 Chieftain and this feature is not detailed.
