|Notes||Designed to be a fast hard hitting Tank Destroyer, the M18 had the combination of good speed and high velocity gun, the chassis was specially developed and the gun was the 76mm M1A2. To achieve high speeds the M18 was lightly armoured. Like all US tank destroyer the turret was opened topped and this kept down the weight. The M18 was built for scoot and shoot tactics rather than standing toe to toe with enemy armour, the 76mm gun was adequate especially if issued with HVAP rounds which gave it better armoured penetration. The M18 served on every fronts.|
