As mentioned in other places , only useful for multiplayer . As for Heavy Tanks and SuperHeavy Tanks more true for the SH they are only really used for their TD version unless you are trying to do something VERY specific . They are BAD value for breakthrough AND their attack values , the only reason you take them is for their hardness . Even if you are Turkey , they take so much steel that you cannot afford it , even when you do not have to import Chromium , in this sense Sweden , and to a lesser extend Spain , are the best minors to do tank stuff with because of their relatively high amounts of steel . As for TDs tank destroyerselfpropelled antitank variants , they are still either specialized or lategame options . An HTD with 5 gun will pretty much guarantee that you can pierce any division which even remotely tries to be cost effective read not ridiculous stuff like heavy tank divisions that cost twice as much as a medium tank division but have half the soft attack because they cut out SPGs to raise the armor level to achieve that . In that sense SHTDs are a stronger , better but slower version of the Heavy TDs . SHTDs are supersweet as I found out recently for two main reasons First of all , no matter how crap your line tanks are , the SHTD will easily bump the armor of your unit above 8085 , which puts it out of the range of any kind of piercing that can be achieved through conventional means Medium TDs , AT guns and right on the edge of that a HeavyTD would be able to pierce . SHTDs , FOR SOME REASON , unlike other TDs are only 1 combat width , making them a nice piece to an oddnumber combat width jigsaw . Heavy TDs also have no problem reaching 100 piercing , meaning they can PROPERLY pierce anything in the game short of VERY dedicated heavy tank or modern tank divisions . And all of this at the low low cost of 700 production cost per battalion , which compares very nicely to a 650 cost for a 2 width battalion of 1941 medium tanks . So on the whole cost of the division , the SuperHeavies are a minor investment that bring A LOT of benefits . Ofcourse the main downside is the research , requiring a 1943 research and realistically you need this stuff up and running by early 1941 if you want it to matter , at least in multiplayer and the fact that they reduce your division ' s speed to a crawl of 4 . 0 kmh . Though interestingly on that last point , 4 . 0 kmh seems to be the absolute minimum a division can go , so even though a 5 armor SHTD SHOULD go 3 . 2 kmh , the division will still travel at 4 . 0 kmh because that seems to be the absolute minimum . The best countries for SHTDs would be a minor capable of producing tanks read SWEDEN , Italy and very maybe Germany or the Soviet Onion . Ideally Sweden and Italy because they play a slightly more supportive role , meaning that Germany can focus on dealing with the hereandnow while Axis supports gear up for a more lategame contingency plan should it be required . On the Allies side it would also be a minor , considering the general lack of armor research bonuses Italy for example gets 4 , Allied minors can get the research by mid 1940 as I tested and executed but lack the resources to actually make use of this . I can see the US typically get to 1943 model of medium tanks which will quite easily reach both 75 armor and 75 piercing , where any 1941 model of medium tank is insufficient and the 1941 heavy tank destroyer barely being sufficient it wouldn ' t take much to chuck in one 1941 heavy or something for the US and push this armor to well over 80 . Also personal conviction that sheer power is typically more useful than mobility goes in favor of the HTD or SHTD , as mobilityrestrictions is in large part down to the air force . The one major drawback is that if the enemy gets air superiority , you have to be quite careful or be liable to losing your divisions to encirclements , but at that point you should really be making the tradeoff between power and mobility . Fun fact by the way , since your divisions with SHTDs will be crawling at 4 kmh anyway , you can do stupid gamey stuff like Marines and Mountaineers instead of Motorized and be supergood attacking in mountains or crossing rivers , don ' t do it myself because tbh it ' s kind of stupid and again hard to plan around since you want to use your tank divisions in a regular way up until SHTDs come out but it will lower division hardness while speed is unaffected , food for thought . ANYWAYS . To sum it up in short , if you want to use Heavy Tanks , use them in small numbers to pump up the armor and piercing of medium tank divisions , thus employing large numbers of medium tanks with only a few heavy tanks because the mediums are far more costeffective in their combat stats . Using larger number of Heavy Tanks in a single division might be and sound pretty cool , but is far more expensive than it is ever worth .
