Armour Guide: 1. Preface

Note: This article is an ongoing project. Therefore, some sections will be missing or will appear incomplete.

Scope

This guide is intended as a help to those with an interest in World War II tanks, who does not feel confident in the finer aspects of armour. Often, arguments used when discussing armour are based on a simplified perception of how armour protection works, and how it is defeated. The purpose of this guide is therefore to be both a primer and a reference.

Sources

To ensure that this guide is as accurate as possible, all information about specific weaponry it is based on the reports and tests made during or immediately after World War II. By doing so, there is little risk of arguing based on knowledge not available during the war. In addition, more recent litterature is used for some of the theoretical background. The most important source for this information are the reports made at the Watertown Arsenal Laboratory (WAL), which was a major research center of the US Army, but other sources of different nationalities are used as well. The list below defines how each source is referred to in the text.
