|Churchill Mk I tank found at: http://someinterestingfacts.net/wp-content/uploads/2013/04/Churchill-ARV-MK-I-300x218.jpg|
The Churchill tank was rushed into production in 1940 when Britain only had 100 tanks to defend its shores, predicatebly there were many teething problems. Armed with first a 2 pounder then 6 pounder guns, they were superseded by 75mm guns from salvaged Sherman tanks, others proving ineffective.
There were many marks of Churchills produced, even one with a 95mm gun, but what stands out are the special adaptations of the Churchill tank which were used on D-Day.They were fitted with flame throwers towing a fuel tank behind, the AVTR carried a bundle of wood to drop into trenches enabling tanks to cross over, they laid bridges and were fitted with a large mortar used to destroy bunkers.
