I. Replacement plan for the T30 to T110 switch.
Case 1: The T30 is researched, but not present in the garage.
- The T30 is replaced by the T110 as the American tier 10 heavy.
- All modules for the T30 are replaced by the corresponding modules in the T110.
- The accumulated experience on the T30 is transferred to the T110.
- Commander, Gunner, Driver: Any of these crew members, either in the barracks or in the tank, who have been trained for the T30 are retrained to the T110 without any other changes or penalties.
- Radio Operator: If this crew member, either in the barracks or in the tank, has training in the T30 as a heavy tank, he is re-trained in the T30 as the tier 9 TD without any other changes or penalties.
- Loader: The crew member, either in the barracks or in the tank, who has the greatest skill level of the pair is retrained to the T110 without any other changes or penalties. The other loader is retrained to the tier 9 T30 TD without any other changes or penalties.
- Player statistics and achievements on the T30 are moved to the T110 without any losses or penalties.
- The player gets an open transition from the T28 prototype to T30 TD on the new American Tank Destroyer branch. This means the T30 as a TD will be researched for the player. (Note: I assume this means that the T30 will be researched in the T28p.)
Case 2: The T30 is researched and present in the garage at the time of replacement. All of the criteria for Case 1 applies, in addition to the following.
- The T30 is replaced in the garage by the T110.
- Ammunition loaded inside the T30 is transferred to the player's depot.
- Consumables stored in the T30 are moved into the T110.
- Equipment installed on the T30 is removed and transferred to the player's depot at no personal cost.
- The player receives the T30 as a tier 9 TD in their garage with no additional modules or consumables, as well as a free slot. (Note: I am not sure if "additional modules" refers to the equipment, such as vents & coated optics, or if they mean actual tank modules. If the latter, there should be no worries as the T30 will be moved in elite form.)
- The crew placed on the T30 at the time of the switch receives re-training in accordance with Case 1.
- The player receives a new, incomplete crew (Commander, Gunner, Loader, Driver) for the tier 9 T30 TD with 100% skill.

II. Replacement plan for the T34 to M103 switch.
Case 1: The T34 is researched, but not present in the garage.
- The T34 is replaced by the M103 as the American tier 9 heavy.
- All stock modules for the T34 are replaced by the corresponding modules for the M103 in the research tree, as outlined here.
- If the engine "Continental_AV-1790-5" has been researched in the T34, then M103 will have the engine "Continental_AV-1790-7C" researched.
- If the turret "T34T7" has been researched in the T34, then the M103 will have the turret "Turret_2_M103" researched.
- If the suspension "T80E3" has been researched in the T34, then the M103 will have the suspension "Chassis_M103_" researched.
- If the gun "105mm_Gun_T5E1" has been researched in the T34, then the M103 will have the gun "120mm_Gun_T122" researched.
- If the gun "120mm_Gun_T53" has been researched in the T34, then the M103 will have the gun "120mm_Gun_M58" researched.
- If the radio module "SCR_528" has been researched in the T34, then the M103 will have the radio module "AN-ARC-27 researched.
- The M103's credit and research costs will be the same as the T34, except for the guns. For example, it will be possible to research the turret "Turret_2_M103" on the M103 at the same experience and credit cost as the turret "T34T7" on the T34 had been. The experience and credit costs of the guns will be recalculated "on the basis of common sense" (Note: likely during Public Test). The gun "105mm_Gun_T5E1", becoming a stock module on the M103, will likely not change in credit cost due to being a module in other tanks. The 120 mm guns will have to have their credit and experience cost recalculated.
- The accumulated experience in the T34 is transferred to the M103.
- All modules from the T34 that are incompatible with the M103 (turret, tracks, gun "120mm_Gun_T53", engine "Continental_AV-1790-5") and those T34 modules in the depot are sold at nominal purchase price, and the credits received in the sale are transferred to the player's account.
- These T34 modules (radio, engine Continental_AV-1790-3, 90mm and 105mm guns) are stored in the player's depot. This applies to all existing rounds in these guns. (Note: This one was confusing.)
- All T34 crewman, either in the barracks or in the tank, are re-trained in the premium T34 without any other changes or penalties;
- Player statistics and achievements on the T34 are moved to the M103 without any losses or penalties.
Case 2: The T34 is researched and present in the garage at the time of replacement. All of the criteria for Case 1 applies, in addition to the following.
- The T34 is replaced in the garage by the M103.
- T34 modules incompatible with the M103 are replaced by modules of equivalent status. For example, if the T34 has the gun "105mm_Gun_T5E1" installed, it will be replaced with the M103 gun "120mm_Gun_T122".
- Ammunition loaded inside the T34 is transferred to the player's depot.
- Consumables stored in the T34 are moved into the M103.
- Equipment installed on the T34 is removed and transferred to the player's depot at no personal cost.
- The player receives the premium tier 8 T34 heavy tank in their garage with no additional equipment or consumables, and a free slot for it.
- The player receives a new crew for the M103 with 100% primary skill.
Updates and further details
UPDATE 1: (Rollup/Tarskin - Confirmed by Overlord) T30 Crew
Because the T30 is moving to the TD line they are planning (according to Overlord) to swap crews a bit. To make things more complicated, the T30 has 6 crew and the T110E5 has 4. As a result, the current plan is to leave the four relevant crew from the T30 on the T110E5. The remaining 2 crew will stay on the T30 (as US TD crew) and 4 new 100% crew (no secondary skills) will be given to the T30.
UPDATE 2: (Rollup/Tarskin - Confirmed by Overlord) T34 Crew
"Your existing T34 Crew will move into the new T34â€. I'm not sure that makes sense, because you can use any tank crew in a premium without penalty to skill, but not the other way around. I'm hoping they will change this and leave the crew with the M103.
This is all subject to change I'm sure, but Overlord stated this in EU Q&A about two weeks ago.
UPDATE 3: (Celestia) Gameplay Stats and Premium Ammo
Added lines predicting the fate of your current gameplay statistics.
Premium Ammo purchased for the T30 will transfer to the T30 TD
UPDATE 4: T34 (Premium) and T30 (TD) Guns
Overlord has said that the T34 Premium will retain the 120mm gun. Expect an ROF reduction but Penetration/Damage is expected to remain the same.
Overlord has said the T30 TD will likely retain the same "155mm Gun T7" it has now and not gain the improved "155mm AT Gun T7" found on the T95. In other posts he appears to say that it will get the better gun but this looks like a misreading of a 2-part question.
Gun Depression for the M103 and T1105E5 will remain "approximately the same" as on the T34/T30 - Overlord.
UPDATE 5: Stats for the 4 New Tanks
T30 (TD) will have researchable modules but it will start out Elite if you have a T30 in your garage at the time of the patch.
T30 (TD) looks exactly the same and retains the turret. Expect Hit Points to drop to 1,700 +/- 100
The M103 and T110E5 have better hull armour than the tanks they replace, but it looks like they don't have much more.
There's a worry that the T110E5's "Colossal Commander's Cupola" will be a significant Turret weakspot, potentially making this new turret weaker overall than that of the T30.
T34 Premium will be available to buy for Gold, price TBC. Might not be on sale at 0.7.2.
T34 Premium will earn Credits at approx. the same rate as other Tier 8 Premiums (I believe this is around 50% more than a normal tank).

The front armour will be made up of several armour groups to reflect the tapering thickness visible below.
