Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The M-III-Y is an American tier 8 heavy tank.

In June 1953, H.L. Yoh Company Inc. presented seven blueprints of a new tank and proposed designs for several of its components. It was planned to use the AOSI-1195-5 8-cylinder engine. The M-III-Y project included a turret with a small frontal projection, a gun mantlet of original design, suspension with horizontal shock absorbers, and an additional track inside the main one that allowed the vehicle to maintain its maneuverability if the main track was destroyed. The project was suspended. No prototypes were built.

The M-III-Y leads to the M-VI-Y.

Player Opinion

Pros and Cons

Pros:

• Decent pen on the T208 Rifled 90mm at 223mm
• Nice shell velocity on the T208 Rifled with 1250 m/s
• Excellent DPM with the T208 Rifled at 2346 base
• Solid armour on the top turret with a small weakspot
• 10 degrees of gun depression

Cons:

• Subpar mobility at 40 kph
• T254 YIII 105mm gun is worse in every regard from the T208 with only the minor alpha damage upgrade
• Low alpha damage at 240 with the T208 Rifled
• Awful gun handling at .24 when moving
• Poor turret traverse dispersion at .13 with the T254 YIII, worse than the T208 Rifled's .09

Performance

The M-III-Y largely behaves in practise like a better armoured FCM 50 t or Tank:A117_T26E5 that trades some of the mobility for much more forgiving armour. While the armour isn't anything to brag about, it is an upgrade over the previously mentioned tanks. The M-III-Y can sidescrape quite efficiently with its 88.9mm of side armour though it does have a small weakspot at the turret ring, though the M-III-Y is rarely played and most players will be unaware of that area.

It is heavily advised to check your allies, if your heavies are significantly faster, then you are better off advancing with mediums to provide fire support. The T208 Rifled shouldn't be underestimated, it can perform quite well against mediums tanks though it does struggle against other heavies due to the low alpha damage. The T254 YIII 105mm is a MASSIVE downgrade in most regards from the T208 Rifled. The penetration drops from 223mm to 208mm, the rate of fire is only 7 rounds a minute, and the accuracy goes from .35 to .37. The trade off is that the 105mm gets 320 alpha damage, which is already subpar for a tier 8 heavy tank. Coupled with the low penetration, the 105mm is far more frustrating. The T208 Rifled 90mm gun can put out an impressive number of rounds a minute (nearly 11 with just a rammer and 100% crew) that can catch mediums off guard and allow you to permatrack most enemy heavy tanks, generating mountains of assistance.

The M-III-Y can be a very strong hulldown tank due to the easily hidden weakspot but it falls behind with its mobility and doesn't get a chance to reach a strong hulldown position before most other tanks will. It also struggles in trades, especially with the T254 YIII 105mm, since it needs to hit a target multiple times to get the same effect. In a top tier game against tier 7s, the M-III-Y morphs into a super strong vehicle. The hull armour is very round and can deflect a lot of lower pen rounds with ease, the gun can shred through the lower HP pools consistently with the high penetration, and the mobility is just enough to push through a flank comfortably.
