Tank Drawing

• Active protection system
The latest generation of protective measures for tanks are active protection systems, particularly "hard-kill". The Soviet Drozd, the Russian Arena, the Israeli TROPHY and Iron Fist, Polish ERAWA (on PT-91), and the American Quick Kill systems show the potential to dramatically improve protection for tanks against missiles, RPGs and potentially KEP attacks, but concerns regarding a danger zone for nearby dismounted troops remain. As for 2011, only the Israeli Trophy active protection system, installed on the Merkava Mk4, has been combat-proven, as it successfully intercepted RPG rocket and various anti-tank missiles during operational missions on the Gaza Strip border.
• Mobility
The mobility of a tank is described by its battlefield or tactical mobility, its operational mobility, and its strategic mobility. Tactical mobility can be broken down firstly into agility, describing the tank's acceleration, braking, speed and rate of turn on various terrain, and secondly obstacle clearance: the tank's ability to travel over vertical obstacles like low walls or trenches or through water. Operational mobility is a function of manoeuvre range; but also of size and weight, and the resulting limitations on options for manoeuvre.
