The OF-40's armour isn't great, but it certainly is in a way better than the Leopard 1's. The OF-40's turret has very weird angles, so you can bounce some incoming shots from there. The sides (excluding the spaced armour in the turret) are only 35 mm thick at most, so you can't rely on the armour as much as you could hope to compared to other tanks that fight at the OF-40's battle rating. The OF-40 has better protection when it comes to the front plate. It is 170 mm thick front-on. Other than that, its hull is very weak, so it cannot be completely relied on. Its survivability is average. In most cases, enemies will only manage to take out one crew member, the gunner and loader are quite spaced out between each other. The same cannot be said about the rest of the crew however. The OF-40 can and will take a hit and with smoke launchers it will survive better than most.

Armor Composition:

• Rolled Homogeneous Armor - Hull and Turret
• High Hardness Rolled Armor - Turret
• Rubber-Fabric Screens - Sideskirts

Armour	Front (Slope angle)	Sides	Rear	Roof
Hull	70 mm (68°) Upper Glacis 50 mm (50°) Lower Glacis	35 mm Upper Crew Compartment 25 mm Upper Engine Compartment 30 mm Lower	25 mm	15 - 30 mm
Turret	30 - 68 mm (Various Angles) Turret front 30 mm (~58°) + 45 mm (Curved) Gun mantlet	Spaced: 30 mm + 80 mm air + 35 mm Forward Spaced: 12 mm + 120 mm + 35 mm Rearward	30 mm	20 - 40 mm

Notes:

• The turret sides use spaced armor, and are therefore stronger than they appear in the armor viewer.
• Beneath the angled outer portion of the gun mantlet is a curved 45 mm plate, which is hard to see in the armor viewer.
• There are 10 mm rubber-fabric screens protecting the upper suspension.

The OF-40 has great mobility, similar to the Leopard 1. It can handle off-road with an average speed of around 40 km/h. On flat surfaces, the OF-40 will reach around 60-65 km/h. It has great static mobility when spaded (not as great when stock). It can keep up with the light tanks and be one of the first to the capture point if you try hard enough.

Usage in battles

Even though it is a medium tank, its armour is very similar to the Leopard 1. The mantlet can bounce or soak some APDS/APFSDS shells but it will usually end up damaging the cannon breech and knocking out 1 or 2 crew members

The OF-40 is an overall great tank that can fulfil most tasks on the battlefield. However, the OF-40 has access to something very powerful: a laser rangefinder, which is unheard of at its battle rating of 7.7. With this, you can range out tanks at very far ranges with ease in less than a second. Measurements given will be much more accurate than the estimate the gunner will give without a rangefinder. This makes the OF-40 a great sniper and it exceeds in this field. Using the mobility, the OF-40 can get to the key positions and sniper spots at a good pace. In the right spot, the OF-40 can apply lots of pressure to the enemy team from a considerable range.

Pros and cons

Pros:

• Good main gun handling
• Has a laser rangefinder, making sniping much easier
• Spaced armour in the turret allows taking some autocannon hits, the mantlet are immune to HESH, and some AP shots bounce if the turret is angled
• Quick and agile tank when upgraded
• HEAT shells combined with the laser rangefinder almost guarantees that you will cause damage

Cons:

• No stabilizer
• Non-ideal stock grind with only APDS to start off with
• Turret, while more armoured than its German cousin Leopard 1, is quite boxy and can be spotted easily if peeking over a ridge line or hilltop
• Only 19+1 rounds in its ready racks, any more ammo is stored next to the driver in the lightly armoured hull and can be easily set off by a penetrating hit
• Slightly below average turret traverse without aced crew

History

After the end of WW2, the Italian industry completely stopped development and production of domestically designed tanks. During the Cold War, the Italian industry would produce armored fighting vehicles for its own needs, however most of these vehicles were foreign designs built under license.

In the late 1970s, Oto Melara and Fiat began developing the first Italian post-WW2 tank, under a join private venture. As Oto Melara was already mass-producing the German Leopard 1 MBT under license for the Italian Army, its engineers possessed sufficient experience and know-how in order to develop their own tank.

The resulting vehicle, designated OF-40, turned out to be, somewhat unsurprisingly, very similar in design to the German Leopard 1 already in service with the Italian Army. Nonetheless, the OF-40 became the first domestically developed and produced Italian tank after WW2.

Despite the many similarities however, the Italian military proved reluctant in ordering the OF-40 for mass production. As a result of being unable to find a domestic operator, Oto Melara turned to the export market and soon found a willing buyer - the United Arab Emirates.

Shortly after, the OF-40 was upgraded to the Mk.2 version which, among other things, improved the vehicle's optics and rangefinder, added a two-plane stabilization system for the main gun, and an improved fire control system, allowing the vehicle to fire improved ammunition.

The OF-40 was only built in limited numbers and for a limited time, with the UAE being the only operator world-wide. The UAE still uses the OF-40 today, although in different roles, with proposals being made to convert the vehicle into a heavy IFV.
