Description

The T-55AM-1 is a gift Rank VI Soviet medium tank with a battle rating of 8.7 (AB/RB/SB). It was introduced in Update 1.81 "The Valkyries".

General info

Survivability and armour

The T-55, which this tank was based upon used exclusively RHA, which proved to useless against advanced chemical warheads. The Soviet Union in an attempt to modernize and extend the service life of the T55, which they had produced so many of, conceived the AM-1 upgrade kit Hence the name of this tank, T-55 AM-1. The upgrade kit consists bolted-on blocks of metal-polymer plates, which are essentially plates of metal sandwiching polymer fillings. This solution was cheap and easy to implement, and its effectiveness was debatable. Compared to the original T-55 (A), the protection is greatly improved, but still prove to be insufficient against certain weapons.

The turret cheeks are fitted with the add-on metal-polymer blocks, which grants immunity to every HEAT warhead in-game except the HOT missiles. The Leopard's 120mm HEAT-FS occasionally penetrates the cheeks, and in that case, very minimal damage is caused. The turret armor against APDS is highly effective, given that the projectile impacts the add-on armor. However, the armor is mostly useless against APFSDS, and in case of penetration, will cause extensive damage.The add-on armor on upper front plate is somewhat effective, as it can nullify HEAT warheads with less than 450mm penetration. Most APFSDS will seamlessly penetrate the hull. Most APDS will bounce.

Do note that the gun breach area is VERY poorly protected by some 200mm of CHA, which is absolutely useless against everything. So do try to angle your turret by facing your cheeks. When doing so, use the right side of your turret to 'catch' rounds, as even if it penetrates, only your loader will die, so no big deal.

Usage in the battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

• Access to APFSDS ammunition.
• Access to very good AGTM.
• One of the few top tier tanks with APHE, great for sideshots (Often One-Hit Kill).
• Battle Rating of 8.7 means it wont face top tier tanks, and is often top dog in 7.7-8.7 matches
• Respectable mobility.
• Decent Armour, especially vs Chemical Munitions.
• Roof Mounted DShK 12.7mm MG is great for taking out low flying Helicopters.

Cons:

• Armour is completely ineffective against APFSDS and 120mm APDS.
• Below average Reload Time for it's BR, many enemies will have a faster reload.
• Poor reverse speed.
• The Rheinmettal 120mm's HEAT-FS and most hih-pen ATGM's will go clean through its armour.
• Mobility, although decent, is worse than most of the enemy tanks you face.
• Still will face 9.7 Tanks, like the Challenger Mk.2 and AMX-40, which outmatch you in every category.
• Ammo stored all around the Hull, a penetration will most likely result in an ammo detonation.
• Rather Weak APFSDS compared to the other ones, will have trouble in uptiers.

History

Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template. Be sure to include links to sources at the end of the article.

Media

An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
