9. In conclusion
During battles tanks would frequently end up in trenches and completely out of service. Tanks were important, however, because they boosted the morale of British troops.
The tank made a minor impact in World War One due to the fact that it was under developed and so unreliable. It did however scare the Germans and it scared them to an extent that they lost moral.
