The tier 6 ARL 44’s armor against its peers and the lower tier tanks it sees can be difficult to penetrate from the front if you treat the ARL 44 like a standard tank. Part of the difficulty with dealing with an ARL 44 is if you shoot at the frontal lower glacis since it is very small and at a 65 degree angle already. Often times you will be aiming down at an enemy tanks lower glacis and thus increasing the angle and in this case it often reaches auto-bounce levels. Luckily the ARL 44 has many other weak spots on its frontal armor and the sides/rear are very easy to deal with. This weak spot guide will show you the easiest places to damage an ARL 44(green), the second best places to focus on(yellow), and the strongest sections of the ARL 44’s armor(red).
Green Sections = 0mm-108mm Effective Armor
Yellow Sections = 110mm-133mm Effective Armor
Red Sections = 187mm+ Effective Armor
Frontally the ARL 44 has a very good armor profile against tier 4-6 tanks and some low penetrating tier 7 tanks since its frontal hull is dominated by a huge upper glacis. The lower glacis beneath it is capable of being damaged by most tanks the ARL 44 sees however as mention earlier you run the risk of auto-bouncing off it since it is very low to the ground and difficult to hit. It is better to instead aim at the machine gun port on the upper glacis which only has 50mm protecting if you are aiming in this area. There are also hull pieces behind the track armor(and 10mm of spaced armor in some sections) that you cannot see but are there if it is the only available spot to shoot at. These areas range from 60mm to 108mm effective armor and the main challenge is hitting the correct areas since you cannot see through the track/spaced armor.
The turret on the ARL 44 is very weak compared to the hull armor aside from the mantlet and a few strips of armor. The turret also has very large 30mm sections of armor on the sides and the roof which can be overmatched by guns 90mm and up. The overmatch areas are highlighted in orange to differentiate them from the surrounding armor and since they are angled at 70 degrees HEAT shells will not auto-bounce but AP/APCR will. The green area around the gun only has 75mm protecting it and the smaller rectangle to the left of the mantlet has zero armor protecting it making it a very easy place to penetrate. The remaining yellow areas on the front of the turret range from 110mm to 118mm effective armor and the small strip on the roof armor bumps up to 133mm effective armor.
Green Sections = 30mm-70mm Effective Armor
Yellow Sections = 80mm-110mm Effective Armor
Red Sections = 132mm+ Effective Armor
The side profile of the ARL 44 is very large and also very weak compared to the frontal armor profile. The only difficultly you will run into here is if you shoot the areas of the spaced armor and/or track armor on the sides that have no hull armor behind them. Otherwise stay away from the frontal turret and gun mantlet area and you will alright penetrating the side armor on the ARL 44.
Green Sections = 30mm-68mm Effective Armor
Yellow Sections = 80mm-116mm Effective Armor
Red Sections = 118mm+ Effective Armor
The rear armor profile of the ARL 44 is also very weak like the side armor profile. The overmatch areas for 90mm+ guns return for the back engine deck and also the entire rear turret. There are hull armor pieces behind the tracks the same way it was on the front, but from this specific view they appear to be very small. From the rear there isn’t any spaced armor plate over these hull pieces behind the tracks and you will be going through 20mm of track armor plus the 50mm hull armor. The only places that might cause bounces are on the upper edges of the commander’s cupola on the top of the tank since they are angled well. Since these areas are very small it is easy enough to just aim at any other spot on the ARL 44’s rear since the entire thing is practically weak.
