The 105 mm Gun Tank M60A1 (AOS) is a rank VI American medium tank with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.61 "Road to Glory".

General info

Survivability and armour

The M60A1 is ostensibly well-protected for a battle rating 8.3 medium tank. From the front, it can resist most types of full-calibre armour-piercing shells, even at the muzzle. Across the turret, line-of-sight armour thickness varies from approximately 200-440 mm, sufficient against all types of 105 mm APDS. Across its hull, line-of-sight protection ranges from 220 mm over the upper glacis, to 280mm on the lower glacis. The upper glacis may be penetrated from 100 mm and 105 mm APDS from ranges inside of 1,000 m, while the lower glacis is completely immune to those shells. The M60A1's own 105 mm M728 APDS can defeat the upper glacis even at 2,500 m, but the lower glacis can reliably stop M728 at ranges exceeding 1,500 meters.

The M60A1 is at risk of being engaged with APFSDS, HEAT, and large-calibre (>105 mm) APDS shells, which may easily bypass its protection, despite being stronger than average. The M60A1 also features numerous weak spots that make it vulnerable to vehicles that would not normally be expected to penetrate its armour. In particular, the mantlet, commander's cupola, and turret ring are vulnerable to APCBC shells, which can instantly destroy the tank upon detonation inside of the vehicle. The sloped turret roof is easily defeated by APFSDS and the vehicle's own M728 APDS, but with some luck, it can cause HEAT-FS and HESH shells to bounce harmlessly off.

The vehicle's armour is optimized for head-on protection. The turret's line-of-sight thickness quickly decreases as more of its side profile is exposed. Likewise, the thin side armour of the hull may be easily overmatched and is also insufficient to protect against most armour-piercing autocannon shells, such as 35 mm DM23 APDS. The roof is resistant to most types of armour-piercing bullets or shells fired by aircraft, but specialized munitions such as German Mk103 30 mm HVAP, or 50 mm AP, will penetrate the M60A1's 20-30 mm thick roof.

When facing an M60A1 head-on, a shell penetrating the left side of the turret may incapacitate the gunner and commander. A follow-up shot to the right side of the turret may strike the loader and first-stage ammo stowage, while a shell to the middle of the hull may incapacitate the driver. Shells aimed at the right side of the vehicle, when being faced head-on, present the greatest chance of setting off ammunition.

When facing an M60A1 from the side, shells penetrating the turret bustle, or hull between the front and middle return rollers, may strike the vehicle's large supply of first-stage ammunition. Some M60A1 drivers may select a reduced ammunition load, so although shells which strike the driver's compartment may incapacitate the driver, they cannot be guaranteed to set off ammunition. Otherwise, shells aimed at the turret between the bulbous rangefinder housing, and before the area where the 25mm flat roof plate meets the sloped 48 mm roof plate, have the greatest chance of incapacitating the entire turret crew.

Usage in 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 instead 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


  • Powerful gun
    • Very accurate gun at long ranges when upgraded
    • Good stock shell (APDS)
    • HEAT-FS and HESH shells available
  • Decent turning capability
  • Very good stock turret transverse speed
  • Great off-road speed (but not as great as Leopards and T-10Ms)
  • Sloped armour can be quite bouncy at range
  • Once fully upgraded it offers very sharp handling and manoeuvrability
  • Excellent acceleration when fully upgraded
  • Gun comes with AOS (Add-On-Stabilizer)


  • Very high profile, made worse by a cupola
    • Commander cupola armour is very large and very thin, can be penetrated easily by APCBC and HEAT rounds
    • Enemy shells can bounce off the turret roof (due to the angle) and could enter the cupola
    • Commander's .50cal HMG is slower in manoeuvrability and not as effective compared to earlier vehicles due to the cupola
    • .50 cal coverage is limited due to commander's cupola
  • Sides are only 41 mm thick, they can be penetrated easily
  • Turret ring can be penetrated by enemy rounds
  • Front is vulnerable to HEAT and the more powerful APHE (T-10M, Maus) at close range
  • No shells with HE core




In 1960, work was started to upgrade the M60 main battle tank, as the T95 project and the project to create composite armor ended. The prototypes fitted the T95E7 turret on the hull of the M60. In order to increase the room in the turret for the crew the gun used the M140 mount, which moved the gun forward 5 inches. The first two prototypes (Pilot 1 and 2) were ready in May 1961, and the third prototype (Pilot 3) was ready in June 1961. The prototypes were designated as the M60E1, and they were all built by Chrysler Defense. Pilot 1 was tested at Eglin Air Force Base, Pilot 2 was tested at Yuma Test Station, and Pilot 3 was tested at Fort Knox. The M60E1 was accepted for American service on 22 October 1962. The designation for production M60E1 tanks was Tank, Combat, Full Tracked: 105-mm Gun, M60A1. Production began on 13 October 1962, with an order of 720 units by the Army.



The upper glacis armor of the hull was upgraded from 3.67 inches to 4.29 inches at 65°. The steering wheel was replaced with a T-bar control, and the break and accelerator pedals were rearranged for easier usage by the driver. The tank was upgraded to the Continental AVDS-1790-2A engine and the CD-850-5 cross drive transmission, and it used the T97 track assembly. The first return roller was moved slightly, and shock absorbers were added to the second road wheel pair. The addition of the shock absorbers was due to the increased weight of the armor and new M60A1 turret.


The main feature of the M60A1 was a new turret, which was the turret of the T95E7 medium tank prototype. The new turret had more armor protection, and it also could had more room for the crew, because of the new M140 gun mount. A fume extractor was added to the rear of the turret bustle, on the left side; this would prevent fumes and smoke from accumulating inside the vehicle when the weapons were fired. The loader and gunner received padded seats, replacing the wire mesh seats which were uncomfortable. Ammunition for the main gun was increased to 63 rounds, with 15 rounds in the turret bustle, several rounds in the turret ring, and the rest stored in the hull. The turret was equipped with a new traversing mechanism, and an AN/VSS-1(V)1 IR searchlight was fitted above the gun mantlet. It received the M19 FCS, which consisted of the M17A1 coincidence rangefinder, M10A1 ballistic drive, and the mechanical M19E1 ballistic computer for the gunner. The M60A1 tank uses the M68E1 105 mm gun. The M68E1 gun shared the same firing characteristics as the M68, but had several design improvements including an updated gun hydraulic configuration, a stabilization upgrade for the gun (but not a full stabilizer), a gun elevation kill switch for the loader, an improved ballistic drive, and other component refinements.

M60A1 (AOS)

In 1972, the M60A1 (AOS) was introduced, which gave the tank an add-on stabilization (AOS) system. It was a kit that could be applied to M60A1 tanks with very little modification to the hydraulic gun control system. The AOS allows for stabilization of the gun vertically and of the turret horizontally. This allowed the gunner to track targets and control the gun and turret while the vehicle was moving; this increased the hit-on-the-move capability significantly. Before the AOS upgrade the fire-on-the-move accuracy at 2000 meters was practically 0%, whereas with the upgrade 70% accuracy was achieved. The AOS had three modes: power-with-stabilization-on, power-with-stabilization-off, and manual. Power-with-stabilization-on was the mode which stabilized the gun, power-with-stabilization-off allowed the turret to be controlled electrically when the stabilizer was not necessary, and the manual mode allowed the crew to still traverse the turret and elevate the gun if the electrical or hydraulic systems were inoperable.
