Credit to Sinenfutorepatolvaj from the EU forums.You have to click the first link, I couldn't get it to embed.These figures represent about how much the armor on the M103 canat 50m. Bear in mind that 50m is very close, and the M103 is probably going to need to avoid CQB all together anyway.Based off of these figures alone, this tank has 2 lethal weakpoints that render it very vulnerable to lower tier vehicles. The Lower hull, which is enormous but *can* be hidden, and the turret front which, fortunately, is relatively small. I don't think an enemy can hit the weaker turret faces unless it is either extremely close [again, something that the M103 should try to avoid entirely] or has extremely good accuracy [which isn't Russian].As it stands, it is vulnerable to heavies and TD's 1 tier below it, but mediums 1 tier below it will have a tougher time. When you think about that though, this isn't in the least bit unusual. The Tier 5 heavies can be penned by tier 4 TD's [not worth mentioning the Tier 4 heavies], Tier 6 heavies *can* be penned by tier 5 heavies and TD's [well see what happens with the T150], tier 7 heavies can be penned by tier 6's [barring the Jagdpanzer IV], tier 8's by tier 7's, and tier 9's by tier 8's [E-75 being the only important exception]. Even the IS-4 can be penned by a Tiger. Tier 10 heavies... you know how that goes.That said, the M103's average armor is not as good as the VK's, E-75's or IS-4's, but its not unusually weak either. The simple fact that tier 8 meds cannot easily confront it... or the simple fact that a KV with the 107 or an M6 with the 90mm cannot take a dump all over your hull armor, almost by itself renders it far superior to the T34. It is true, the turret armor is not as effective as the T34's. However, at the ranges that the M103 should be attempting to engage the enemy this almost becomes a complete non-issue. The accuracy and pen increase certainly helps on this front.It, of course, is also true that the M103 is probably going to get trashed in a well-played CQB [though in a 1v1 knife fight its DPM may give it an edge]. This, again, does not put it in an unusually poor position. Think of a tier 9 Tiger H or AMX M4, only your armor isn't THAT weak and your gun depression isn't THAT bad. The opposition will wreck you in a close quarters CQB. Just remember that you're better than any of them at anything else [barring the AMX], though the E-75 can snipe pretty well.On that note, personal prediction; The E-75 is going to be notable for being OP compared to the other tier 9's once the IS-4 goes tier 10. I'm not too sure how the ST-1 is going to turn out, according to speculation its essentially an IS-4 only with thinner side armor and turret armor. I know I'm getting off topic here, but based off of the previews the driver's hatch its on that thing is also enormous and the side of your turret is huge.
