The M4A2E4 (AKA: CBT, CB tank, Sir ROFL) is our reward for the closed beta test. Many have soled it or bad-mouthed it. Many laugh at it. Then again many cant use it .
Tank specs:

Its tree:

Overview:
The M4A2E4, being a premium tank, is better than a stock T5 medium but worse than a fully upgraded T5 medium. It has a premium version of a M3 Lee upgraded gun, has thick and sloped frontal armor but pathetic side and rear armor, is relatively mobile, good radio and view range.
Important: Try not to sell this tank as when the sell tanks feature is here, it might just well cost you a fortune.
Price: Gift
Camouflage: Good
Pros:
-Great frontal armor
-Good rate of fire
-A good bully tank
-Good money-making abilities
-Great when fighting tier 3-6 tanks
-Powerful HE
Cons:
-Bad penetration
-Not that accurate
-Balance hates you… gl & hf killing the King Tiger over there
Designation:
1. Warrior
2. Steel Wall
3. Confederate 
Crew:
1. Commander

2. Gunner

3. Driver

4. Radio Operator

5. Loader

I suggest you specialize your crew this way:
1. Repair

2. Camouflage

3. Firefighting

Being small and not that hard-hitting i suggest you for camouflage as secondary skill. Fires are very rare anyway.
Modules
Armor scheme of the M4A2E4
Spoiler
Hull: Greatly armored at the front, but bad at the sides and rear. Most tier 3 tanks (except Murder II), most tier 4 tanks (except Hetzer and SU-85B) and even some tier 5 tanks will have a LOT of trouble dealing damage at the front. Sides and rear are minced-meat.
Suspension:
M4A2E4T42 . Max.capacity: 33.3 (T) / rate of turn 37 deg / sec
Good enough and you can mount some more equipment too.
Engine:
GM 6046 engine . 410 hp / 15% chance of fire / 549 kg
A power to weight ratio of 12.9 is good enough to feel mobile when you have to.
Radio:
Radio Station SCR 508/1.range 650m
Its good almost all the time
Turret:
M4A2E4 D51066
Armor 89/50/50mm
45 deg per sec /
View range of 420m
Good angle and mantlet make this a tough nut for most tanks of the same tier, though sides and rear are pretty much unprotected.
Guns:

Same as the M3 Lee upgraded (unfortunately it isn’t researched for the M3 if you have the Sherman) which is not good… you will have problems killing Hetzers and Leopards and other shermans. PZ4s and T-34s don’t seem too hard. PZ ¾ will bounce a lot. KV if aimed right can be penned easily, so can T1. Arty at tier 4 and less are 1-shotable by the powerful HE shell.
Comparison with it peers
M4A2E4 vs M4 Sherman
The M4 MUCH worse armor. Its shape and thickness just aren't equal to the M4A2E4. Stock M4 is very weak compared to the CBT, but a fully upgraded one has access to the 105 and 76mm guns which are miles better than the M3L. Upgraded it also has as a whole better mobility and acceleration thanks to a superior engine, though when going down-hill you will have the advantage as the M4A2E4 has a little higher top speed.
In short
M4A2E4 is a great ramming tank, better than M4 (i have 1 kamikaze in it)
M4A2E4 is better than stock sherman but is worse against higher tier opponents.
Both make a lot of credits, but CBT does earn more
Usually M4A2E4 wins 1v1 engagements against sherman, no matter the upgrades
M4A2E4 vs PZ IV
The Panzer IV is much weaker when stock, but packs a serious amount of fire power once with the 75L70 or 105 mm gun. The CBT out guns the IV until it has the 75L48, but still has a higher DPM. Both tanks have good armor at this tier, but again the M4A2E4 has better frontal armor.
In short
M4A2E4 is better than stock PZ4 but is worse against higher tier opponents.
Both make a lot of credits, but CBT does earn more
M4A2E4 wins most 1v1 engagements no matter the PZ4 equipment.
M4A2E4 vs T-34
M4AE4 wins 1v1 engagements no matter the upgrades on T-34. T-34 is faster and more accurate with more penetration, but you still have more armor.
In short
M4A2E4 is better than stock T-34 but is worse against higher tier opponents.
Both make a lot of credits, but CBT does earn more
M4A2E4 wins most 1v1 engagements no matter the T-34 equipment.
M4A2E4 vs PZ3/4
Both have about the same armor. PZ3/4 is faster and more maneuverable. Both are good vs smaller tanks, though turret on PZ3/4 is a possible weak-spot
In short:
Both arent really good vs higher tier opponents, though PZ3/4 is a little better when fully upgraded
1v1 its PZ3/4 victory mostly
M4A2E4 is still better at credit making.
Historical M4A2E4 in battle
The M4A2E4 was made to be a lend-lease tank for exportation to other countries like the Soviet Union and Great Britain that used gasoline engines. It also has a very advanced suspension system, that was very difficult to maintain. Only 2 M4A2E4s were ever made. That doesnt stop them from being used in historical battles (check them out, here on the forums) as just of another sherman tank so it does pass. Its great when facing historical PZ4s and can kill a tiger from the side.
Suggestions to the developers:
-Buff accuracy to 0,37
-Buff acceration
