GarageImage M13 40 (I).jpg

The Fiat-Ansaldo M13/40 I Serie (shortened to M13/40 (I)) is a rank I Italian medium tank with a battle rating of 1.0 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic". Its default colour is grey.

The M13/40 (I) is typically used as a breakthrough tank or a "blockade runner" due to the fact that it is very resistant to enemy fire especially when angled and can disable or destroy enemy vehicles with only one shot when up close. Beware, however, around the 500 m mark, the cannon ammunition starts to lose its punch and can fail to penetrate effectively.

General info

Survivability and armour

All of your armour, which can realistically be targeted, is flat, so despite quite high frontal armour values the M13/40 (I) must always be angled when squaring off with an enemy combatant or risk direct shot penetration of your vehicle. Your side armour value is not as good as the front, but at extreme angles, it becomes more effective.

As long as you angle your tank right, you will have 36 to 50 mm of effective armour thickness and use it to block enemy shots. Destroy British tanks and any SPG as soon as possible, as every single one of them can destroy your tank. It is also worth destroying Soviet and certain USA tanks first as well, however, not every one of them can penetrate your armour.

The rear end is also rather long, so enemies could pick this piece off if it is exposed. But it's better to be shot at your engines, than your crew compartment, located in the middle of the tank. Don't give your opponent any time to do that and make them go away before they started firing onto your second tier.

Mobility of the M13/40 (I) is horrible on anything but flat land, but it's okay as long as you don't try to climb steep hills or to cross the entire map fast. Attempting a steep hill flank will just get you stuck and leave you exposed to enemy fire.

  • The APHE shell is good enough for flank shots and direct shots at flat armour up to 500 m. Post-penetration effect is enough to destroy most opponents of rank 1 with one or two shots.
  • The APBC shot does not have increased performance against flat armour, however against angled armour it does increase your chances to penetrate turrets along with angled armour and damage enemy tanks at longer range.
  • Overall, almost nothing can deflect your shots at 100-200 m range.

Usage in battles

Try to push through enemy fire, while being angled at least 30° to your enemy. Destroy anyone who dares to fire at you, specifically targeting SPGs and those who forgot to angle their armour. Upgrade your ammunition for a better damage profile.

Alternatively, take a slightly flanking direction near to your team and use your strong characteristics to intercept any fast-moving vehicles while moving along with your team. After finishing the cleanup, flank main battle and destroy defenceless opponents.

It's not worth fighting heavily armoured vehicles alone while being angled without upgraded ammo. At a range of 500 m, you will probably only penetrate each other's turret and it's more up to luck than anything. One possibility if fighting from this range, your shell can potentially incapacitate turret crew, disabling the tank and allowing a team member with heavier firepower to finish the target off without the threat of being fired upon.

Tanks equipped with autocannons can destroy you from the rear and sides, however, they often go for engines first. Keep an eye out for them.

Pros and cons


  • When angled, can take shots from most 1st rank tanks without consequences
  • Can destroy tanks fast, if penetration is possible
  • Very thick mantlet - about 40+30 mm overall, but be aware that at long range shells drop at an angle, and at places its protection becomes less than 30 mm
  • Excellent gun depression


  • Engages in eternal shootouts with something with the same armour level as itself
  • Slow and unable to climb well
  • While being slow, you are also forced to always drive at an angle as not to allow someone to set up for a direct shot
  • Slower reload compared to other reserve tanks.


Intended to replace the unsatisfactory M11/39, the M13/40 retained its main mechanical features, but with a more powerful gun in a fully rotating turret. The M13 was slow, unreliable, and suffered from the tank commander doubling as the gunner. Similar to early Russian and French tanks, it did not receive radios as standard equipment until 1942. Nevertheless, it became the standard Italian medium tank from 1941 on, and is the best known Italian tank of the war. In War Thunder, the M13/40 (I) represents those made earlier in the production run, with manual turret traverse instead of hydraulic traverse gear. Reportedly Italian crews would remove the hydraulic traverse, which was cumbersome; the (I) model has extra ammo storage to reflect that.

It first saw service with the 3rd Medium Tank Battalion (Battaglione Carri M) in Libya's Sollum-Halfaya region. It later equipped 132nd "Ariete (Ram)" Armoured Division (Divisione Corazzata) in North Africa. From January to April of 1941, it also saw action in Yugoslavia and Greece with the 131st Centauro (Centaur) and 133rd Littorio armoured divisions. For a short time after the first rush of British victories in North Africa in early 1941, there were enough captured M13s to equip a British armoured unit, 6th Royal Tank Regiment, in Libya. These were all lost in turn to Rommel's offensive in March of that year. In late August of 1941, Italian medium tank platoons increased their number from four to five.

When Italy surrendered in September 1943, 22 M13s were captured by Germany, who handed them over to the Italian fascist forces. It is uncertain how many in total were produced, as many were converted to M14/41s: estimates range from 710 to 1,049.
