Description
The Ordnance BL Tk. L11 is a British 120 mm rifled cannon derived from the Conqueror's L1A2 120 mm main gun. This powerful gun was meant to be used in the Chieftain series Main Battle Tank, in-game this cannon is present on the Mk 3, Mk 5 and Mk 10 variants of this vehicle. At time of production, the L11, firing armour-piercing discarding sabot rounds (APDS), was one of the most fearsome anti-tank solutions present in an Armoured Fighting Vehicle and thus, fulfilled its purpose to defeat the 60s Soviet armour.

Comparison with analogues

Usage in battles
Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.
Pros and cons
Pros:
- The APDS round has high penetrating power, able to defeat all but the most heavily armoured MBTs it encounters.
- Has access to HESH ammunition, being capable of overpressuring and destroying lightly armoured vehicles in a single shot.
- The L21A1 12.7 mm Heavy Machine Gun can be used alongside with the main gun to accurately rangefind targets for the HESH due to the similar ballistic performance of both rounds.
- Late vehicles (namely the Chieftain Mk 10) have access to APFSDS ammunition
Cons:
- Slightly less accurate than smoothbore counterparts
- HESH shells produce little spalling, making them impracticable to fight heavy vehicles
