Description

The FIAT 6614 (M40A1) is a rank IV Italian light tank with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic".

General info

Survivability and armour

Armour type:

• Rolled homogeneous armour (hull)
• Gun steel (gun barrel, MG)
• Wheel (tires)

Armour	Front (Slope angle)	Sides	Rear	Roof
Hull	8 mm (30-46°) Driver viewport 8 mm (70-81°) Upper Glacis 8 mm (52°) Lower Glacis	8 mm (21-45°) Top 5 mm (12-20°) Radiator vents 8 mm (25-33°) Bottom 8 mm Wheelwells	8 mm (17°) Upper plate 8 mm (43°) Lower plate	8 mm (9-20°) Front Glacis 8 mm Crew compartment
Gun mount	8 mm
Cupola	8 mm

Notes:

• The gun barrel is 25 mm thick.
• All windows are 8 mm thick.
• The tires are 10 mm thick.
• The belly is 8 mm thick.

The FIAT 6614 has almost no armour, like other vehicles in the Italian tree, and with that very low survivability. Anything that hits a side shot will knock out at least one crew member, while a frontal or rear shot will incapacitate a minimum of 3 crew, enough to take the player back to the hangar.

The average effective thickness changes depending on where the FIAT 6614 is shot from. At the front, it ranges from 15-20 mm thick, although the front-facing window of the driver's hatch does only give 9 mm of armour between a machine gun round and the driver. While a 7.62 mm round will only penetrate at close range, a 12.7 mm heavy machine gun round will only fail to penetrate that window at over a kilometre away. Considering the car's most valuable advantage is its ability to get to good positions fast, an incapacitated driver will ruin the FIAT 6614's chances in the match.

The side's obvious weak spots are the grills near the front that are only 5mm thick. Considering that the vehicle has a hexagon-shaped cross-section if sliced from left to right, the upper plate of the slanted side offers 9 mm of protection after the grill and 10-12mm around and in front of the grill. The lower side plate gives a whole new world of armour with a minimum thickness of 10mm everywhere, which means at least the 7.62 mm machine guns can't penetrate the car through there. The doors have the same thickness as the rest of the sides.

On the back, there's one slanted plate that is 8 mm at the top which increases to 14 mm at the bottom. Again, like the sides, the door doesn't have a different thickness. Also, the gun is very easy to disable as it has a maximum effective thickness of 88 mm, which all tanks at this BR will be able to penetrate and disable in one shot.

This tank is still very vulnerable to strafing aircraft. Bombs and rockets also deal heavy damage if the FIAT 6614 is standing in their destruction radius.

Mobility

Game Mode	Max Speed (km/h)		Weight (tons)	Engine power (horsepower)		Power-to-weight ratio (hp/ton)
	Forward	Reverse		Stock	Upgraded	Stock	Upgraded
Arcade	112	22	8.7	225	305	25.86	35.06
Realistic	100	20		128	160	14.71	18.39

The FIAT 6614's mobility is very good. The fastest speeds it can reach will depend on the terrain: on a track like the ones on Sinai, the FIAT 6614 can easily reach 60 or 70 km/h, and driving on an actual road or going downhill it will reach the 80's or 90's; but on a grassy field, it may only reach up to 45 km/h. Due to the FIAT 6614 being a wheeled car, going through sand, snow or a small uphill will trickle away its speed. The wheeled construction means the FIAT also cannot neutral steer, but it does have a small turning circle (tank-sized) and it can turn in this circle at 23 km/h.

When reversing the FIAT 6614 has good acceleration as well, reaching -10 km/h after about 3 seconds and will get to -20 by the fourth second.

Notes:

• Rounds are modeled individually and disappear after having been shot or loaded.
• Full ammo load should be brought for the cannon because running out of shells is very common in this vehicle.

Machine guns

The M80 machine gun is your standard .50 cal, except for the fact that its clip size is extremely small, making it not very effective against light armored vehicles, and aircraft. However, the velocity of the ammo is similar to the main armament, allowing it to work as a quick and short distance rangefinder before you fire.

Usage in battles

The FIAT is a light tank destroyer with extremely potent anti-tank grenades that is almost guaranteed to slice through any armored foe. Never put yourself on the front lines as your armor is not up to the task of taking on anything heavier then .30 caliber machine guns, however, striking from the shadows is the best option. Due to the excellent penetration of the anti tank grenades, this tank destroyer is best played pointing and shooting at the target, not minding weak spots.

Pros and cons

Pros:

• 106 mm HESH is enough to one-shot most enemy vehicles, aside from some heavy tanks
• 360-degree turret transverse
• Fast on road
• Small target, easy to hide
• Can swim

Cons:

• Very thin armour, 12.7 mm can penetrate it frontally
• Bad off-road speed
• Cupola blocks turret elevation when traversing the turret
