tanks

n. large receptacle in which liquids or gases are stored; armored combat vehicle; prison cell (Slang)

A tank is a tracked armoured combat vehicle designed to engage enemies head-on, using direct fire from a large-calibre gun and supporting fire from machine guns. Heavy armour as well as a high degree of mobility give it survivability, while the tracks allow it to cross even rough terrain at high speeds.
