Hi, and welcome to the guide.

If you are here, you are most likely wondering why you cant pulverize your enemies with your invincible tank or the likes. This tank is NOT invincible and i will be touching on that later.

This is a bit of a read.
Mfw i just got this tank

First off, this tank is mostly a sniper vehicle.
It has thick armor which is best put to use at a long range, and a powerful gun which too has great penetration, even at long range. It's semi-decent maneuverability allows it to reposition from sniping spot to sniping spot, and to retreat if spotted.

But this tank is NOT invincible. If you are careless and dont angle your armor, you will die. quickly.

But, That doesnt mean you always have to be a sniper.

Your acceptable reload speed, clocking in at 8-9 seconds (depending if you have a upgraded crew), allows you to brawl enemies and come out victorious. When brawling medium tanks, always have the 1st shot on them and make sure to have them immobilized or crippled before finishing them off with the 2nd shot.

But due to how powerful your gun is, you may as well just 1 shot it and move on to another hapless victim which is right 'round the corner. Shermans will fall to your gun, and a smile of SWEET satisfaction will fall upon you as you slaughter KV tanks and T-34's left and right (while they were invulerable to your puny 50mm gun of your panzer 3's or bouncing the panzer 4 F2 (and above)'s 75mm gun). Sweet revenge, it is.

But one thing you should never do,is be separated from your allies.

A lone heavy is a dead heavy. You arent very maneuverable, and being that far in enemy territory will result in a medium tank flanking you and possibly killing you. Best thing you can do is kill as many vehicles as you can to allow your team to catch up and do something instead of cowering in the spawn like a bunch of ♥♥♥♥♥♥♥ morons.

another tip to help you survive, if you are in a firefight. this will help, even if you are at a long range. Angling. Angling essentially means point a front corner of your tank at a enemy, so that your front armor will be penned less easily, same goes for your side armor. Make sure to angle enough so that your side armor is not a target, and that your front armor is hard to pen.

A quick run-down.

It is a excellent sniper, with a powerful and accurate cannon
A good brawler, with a decent reload speed and competetive turret turn rate for a heavy tank to quickly destroy enemies around the corner,
A good ambusher, (sitting around a corner as some hapless noob charges ahead only to die by your hand)
and in general, a good tank overall.

APCBC is the best shell for you.
I wouldn't use HE, but personal preference.
Dont bother using HEAT, it is useless.

However, the latter 2 shells are useful against vehicles with no armor, like Nashorn, M18 and SPAA.

Ignore the mobility mods, and get the parts and fire extinguisher mods.
Then research the mods that will help you in combat.

(Tanks listed arent in Light, Medium, Heavy, TD, SPAA order)

Russia:
KV-2
This sucker will kill you and your entire team if you dont take him out. TOP PRIORITY TARGET.
IS-1
A dangerous enemy, as his armor has a good chance to eat up your shell and a stupid bouncy turret which will trololo you as he shoots you once at close range and you die.
IS-2
Basically a IS-1 with a 122mm gun. Take great caution when fighting said tank. It can 1 shot you, any distance. Luck and getting the 1st shot off is a must. or you die. instantly. Preferably, let panthers or tiger 2's deal with it. Their guns have a bigger chance of penning at long range. (Includes IS-1's but they're weaker than IS-2s.)
T-34-85
A little bugger. It can outflank you and your team, and proceed to get shots into the juicy sides of you and your allies. If you find him, hope that RNG doesnt make his armor bounce your shell when it hits dead on and blast him to bits. Make sure he doesnt get a shot on you.
KV-85
Think of it as a downarmored, lower tier, less maneuverability IS-1. Doesnt mean it can still 1 shot you. Its armor is pathetic, due to being a KV-1 hull. shoot it's driver port (or any of its hull) and it will die.
SU-152
A gun the same calibre of the KV-2's, except that this thing can actually penetrate armor better. weak armor, and if it is angled, shoot it's little cheeks for insta-kill. It can still 1 shot you like the kv-2 can.
SU-85 (both models)
Cannon fodder. Shoot it anywhere. (dont get shot at tho)
Lower tier T-34's
cannon fodder.
T-44
Your only hope is turret pen. or side armor pen if he angles too much.
IS-3
Matchmaking really screwed you over. shoot the triangle right below the turret. (Dont shoot the pike nose)
T-54 mod 1947
Well, you are screwed. MM screwed you over again, yes? Shoot turret and hope it pens.
ISU-122
A IS-2 tank destroyer. Just shoot it anywhere. except the mantlet thingy.

USA:
M4A2
A rare sight, but you can come across time to time. Shoot it anywhere, and it's gun is a popgun at 5.7
M4A1 (76) W
Essentially, a up-armored and up-gunned M4A1 tank you fought in a panzer 4 F2. Your gun will go through its armor, guranteed. It can bounce if you dont shoot it in the correct spot. Dont shoot turret mantlet.
M4A2 (76) W.
Same thing as with the M4A1 (76) W, except it doesnt have a rounded hull. Dont shoot turret mantlet.
M4A3 (76) W HVSS
Same goes with all the 76mm shermans. Be careful, it has APCR and NEVER underestimate it.
M6A1
It's armor may eat up your shells if you are being stupid.
T25
A prototype pershing. Think of it as a upgraded sherman. the 90mm gun will 1 shot you, so be careful.
M18 hellcat
Initial D intensifies. Dont let it flank you and pump 76mm shells into your side armor. or you die.
M26 Pershing
The true pershing, not a common sight. But be prepared to get 1 shot. It's armor is comparable to yours, but it is sloped. Shoot lower glacis or the MG port.
T-29
:( well, shoot it's lower glacis and hope for pen. or shoot it's gun and let your heavier allies do the work.
M41A1 Walker bulldog
APDS is painful. shoot it anywhere.

Britian:
Comet
Its fast, and has APDS. It stings. But it has sad armor at 5.3.
Sherman Firefly
Uses the M4 sherman hull. No armor, whatsoever. Shoot it anywhere.
Black prince
Uncommon sight. It has the 17 pdr gun, so be careful. And it's armor is impervious to your gun at medium/long range.
Churchill mk VII
Same goes with black prince, but without the 17 pdr gun.
Challenger
Cannon fodder. But it has a 17 pdr gun, so it is still dangerous. Do not underestimate.
Avenger
No armor. shoot it anywhere. But dont underestimate, it has a 17 pdr gun.
Tortoise
Only seen if uptiered. You have 0 chance against it. If you dont know it's weakspot, that is.
Shoot the commander's cupola on it.
Centurion mk 3
A rare sight, same BR as the pershing. It doesnt have any shells with HE filler, so thats good. It carries APDS, however. Shoot lower glacis. why would you shoot the turret?
the STRV (or the STD, as i like to call it)
Just a centurion mk 3 with 3 atgm's. Shoot lower glacis.
Carnaeveron
Think of it as a up-armored Centurion mk 3. Lower glacis is a tasty taarget.

Germany
Tiger H1
It's you. Get the 1st shot off, and try to hit the hull's front armor (shoot the corner closest to you for maximum damage) or shoot cupola, or lower glacis
Tiger E
Same tactic as described for tiger h1, except it has tracks on lower glacis and a better cupola and a up-armored mantlet.
Panther D
Brawl it or shoot it's mantlet.
Panther A
Shoot it's mantlet or cupola. MG port if close enough.
Panther G
Mantlet looks like a good choice, but cupola is better. MG port if close enough.
Panther F
No mantlet, but turret front is 120mm thick. It has a fast reloading gun. MG port if close enough.
Panther II
Dont even bother with upper glacis. It can and will 1 shot you. turret thickness is same with panther F, and lower glacis is a enticing target. but i wouldnt shoot at it if your gun doesnt pen enough.
Nashorn
Tiger 2 gun at 5.3. No armor whatsoever. (So your shells MAY overpen. shoot HE, but APCBC at the correct place is fine.
Dicker max
Oh boy. Insane gun depression. It's gun can 1 shot if it pens.
Hetzer
Lower glacis.
Jagdpanzer 4
Lower glacis or hit the superstructure.
Panzer 4/V
a jagdpanzer 4, but with a panther gun. Especially dangerous.
Jagdpanther
Essentially a panther hull (G variant) with a 88mm pak 43.
Ferdinand
You are ♥♥♥♥♥♥. ;-;
Tiger 2 P
shoot the turret, ASAP
Tiger 2 H
You are ♥♥♥♥♥♥ even more :(
Steuer Emil
Think of it as a bigger dicker max. Its gun will 1 shot you as much it wants to, but it only has 15 shells. Use that to your advantage.

If this guide didnt help, there should be other guides to help you play this tank effectively.

tell me if i missed anything.

Not so fast.
Thought you could skip, huh?

Shame on you, go back and read, you lazy git.
