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 T28 Prototype is an American tier 8 tank destroyer.

Early prototype of a heavy tank designed for breaking through fortifications of the German Siegfried Line. Existed only in blueprints, prepared under the program for developing heavy vehicles that was initiated in September 1943.

The T28 Prototype has a decent gun, good penetration and a useable ROF. Like the T28, the Proto is very very slow, if caught in the open there is no chance to survive and reversing will do no good. You do have good armor; however it is not as good as the T28, yet it received an closed top in 9.14, making it slightly less vulnerable to HE and artillery. Do note that although it has a turret, it can not rotate 360° and is very slow, meaning it will not help much against circling enemies.

The T28 Prototype leads to the T30.

Player Opinion

Pros and Cons

Pros:

• Acceptable top tier gun with decent penetration and handling
• Excellent rate of fire and wide fire arc for a TD
• Excellent frontal armor if enemies don't know the weakspots, especially if it can be angled while hiding side armor
• Intimidating opponent, especially if faced head on by mediums or lower tier heavies
• From 9.15 patch on, it was modeled with an enclosed turret. It's more resistant to SPGs and can use Improved Ventilation.

Cons:

• Slow traverse and speed (plus low camouflage) make you an easy target for SPG and flankers
• Accuracy and alpha damage are subpar if not bad for its tier
• Armor suffers from gold ammo and is not entirely reliable with multiple large weakspots
• Horrendous stock grind (occasionally useless in tier 10 battles with stock configuration)
• Turret cannot rotate through 360 degrees

Performance

It is very similar to the T28, especially in its speed. While flat surfaces are 51mm thinner than that of the T28, these are still roughly proof against most medium tank guns in tier and most guns below its tier. With its fast firing 120mm cannon and good gun depression, the T28 Prototype shouldn't be underestimated, especially in hull-down position. Its closed turret also makes it more resilient to artillery, but make sure you're staying in cover as much as possible to increase the odds of survival. Yet it's important to note that the turret can only traverse a total of 286° degrees, which can be a major disadvantage if a medium or light tank gets to circle you. Also, its side armor, even if seemingly rather angled, won't necessarily deflect anything as it only holds 50.8mm of thickness, which translates to only little more than 100mm effective thickness outside auto-bounce range (sides no longer are overmatched by 152 mm shells, since the thickness was increased by 0.8mm). As for prototype users, don't expose your sides when facing the front unless it's necessary to do so.

Although a great supporter, if top tier, it can brawl and beat even some tier 8 heavies. Most of them cannot reliably penetrate your front without resorting to weakspots, but only brawl if a flank was left open or your team's heavies were destroyed. As a sniper, it will devastate tanks out in the open. Shooting unsuspecting tanks will scare the crap out of them, Especially when top tier. The 120mm gun's reload is outstanding. Many expect it to take longer than 9.68 seconds, and will leave themselves exposed because of this. You will need to take advantage of this, as it will allow you to deal a lot more damage. Flanking, however is still a problem. The turret traverse and hull traverse combined is still too slow to keep up with the faster ones. One daredevil tactic to use on flankers is to turn your hull into them. This will wipe out at least their tracks, if not reducing their HP pool greatly. But if you miss the flanker, you will have blown your chance to defend yourself and should only be done if support is coming and you have full HP.

Early Research

• You should aim to unlock both guns before moving on to anything else. The starting gun is wholly inadequate, while the 120mm makes you a destroyer of worlds. If possible, use free XP to get the 105mm gun so you don't have to use the 90mm. Alternatively, you can unlock the 105 mm on the T25 AT.

Historical Info

In 1945, a turreted variant of the first T28 was planned. It was planned to mount a big, heavily armored, limited-traversed turret that can only traverse 286° degrees. The planned turret armor ranged from 4 inches (102 millimeters) to 8 inches (203 millimeters). The gun to be mounted was the 105 mm T5E1, the same gun the T28/T95 had mounted, and it can elevate 15° degrees, and depress 10° degrees from the turret. The suspension was changed to use the M4A3's Horizontal Volute Spring Suspension (HVSS) because the Vertical Volute Spring Suspension (VVSS) proved to be obsolete for the tank's weight. The HVSS suspension proved that it distributed weight more widely. Planned hull armor ranged from 2 inches (51 millimeters) to 8 inches (203 millimeters). The tank was planned to use the same engine as the T28/T95 had used, the Ford GAF, a V8 gasoline engine which produced about 500 horsepower. The tank housed a crew of five. No prototypes or blueprints were ever produced. This was because during the later stages of T28 development and evaluation were overtaken by that of the T29 and T30 turreted heavy tank design. The T29 mounted the same gun as the T28 in a conventional rotating turret. The T30 was developed with a larger-caliber gun and more powerful engine. Due to this the T28 program was terminated in October 1947.

Historical Accuracy Errata

The following are consensus errors or inconsistencies which have been identified with the configuration of the vehicle in question and conflict with information available on the public record. The causes for these divergences in the game are normally not disclosed and may be rooted in game balance.

It is generally agreed the T28 Prototype as it exists in the game is considered to be a fabrication based on liberties taken with various T28/T95 program proposals.

• The T28 had no turret.
• The 105 mm AT Gun T5E1 is the T28's only historical gun which it still carries today. The other gun configurations are fake.
• The T15E2 gun was only mounted on the T26E4 SuperPershing.
• The T53 gun was only mounted on the T34.
• Ford GAF engine is considerably more powerful than in reality, with 670 hp compared to the historical 500. The 780 hp engine configuration is fake.
