Stats dump, but not a lot of arguments.
Both M48 and T-54 have a lot of armor, but it is negated by HEAT. No armor, best armor.
T-54 and M48 have more much more firepower when they can pen with APHE. On M48 though APHE isn’t really practical, because of how low the penetration is. T-54 is quite unique in that regard, it didn’t get rid of a very powerful APHE, but still sometimes APHE just isn’t enough.
When APHE isn’t enough, their firepower becomes comparable. M48’s 90mm HEAT deals less damage and has less pen, but has better reload. T-54 has slightly better reload, but also slightly less pen and damage. Pen isn’t that important here, as it does the job for all tanks compared here, only M48 might struggle sometimes.
All tanks have comparable mobility.
In therms of mobility, this is the 1 area where M48 stands out, being much faster in practice than T-54, while also having good turret and hull traverse speed. However, M48 is also the biggest.
I don’t know exactly how Ikv 103 handles, but it’s probably overall the same as M48, having higher top speed, but also a weaker engine. It has the best reverse speed out of the 3 though, which is quite important.
While M48 and Ikv 103 have good gun depression, T-54 is lacking in that regard, making it awkward to use in some positions. T-54 is the slowest out of the 3 and has horrible turret traverse speed.
M48 has good gun depression, but it’s very big, while T-54 is quite small for it’s class, but has poor gun depression. Ikv 103 is both small and has good gun depression.
Ikv 103 lacks good zoom compared to M48 and T-54, but I personally don’t care about zoom in a tank. It’s a nice bonus.
Shell velocity is a bit of a problem on Ikv 103. I believe it will make you miss sometimes, but also isn’t bad enough to make aiming a struggle
I would rank them like this:
- T-54 (1951)
- Ikv 103
- M48 (the gun is just too bad for it’s size)
T-55A is quite a big step up, because of the stabilizer and improved turret traverse speed. A better engine also doesn’t hurt. It was generally a very good tank for it’s time and is rightfully 0.3 higher than T-54s. It probably should be 0.7 higher, 0.3 is for the historical reasons and another 0.4 for the balance reasons (stabilizer).
Leopard 1, in my opinion, completely outclasses all tanks above, except T-55A purely because of the stabilizer. It just has excellent firepower, mobility and handling. Armor is good enough to stop most of the “noise” like MGs, some SPAAs or poorly dropped bombs and arty, but is thin enough to not slow you down. The only thing it lacks is a stabilizer.
Now assume 6.7 ends WW2 and 7.7 ends conventional armor/shells era (IS-4).
If BRs were decompressed, I would put M48, Ikv 103 and T-54 (1951) at 8.3, T-55A at 9.0 and Leopard 1 at 9.7.
Starting from 8.3, to make a little more room for Cold War, but conventional tanks like AMX-50s for example. They would fit perfectly in 8.0, acting as a link between eras.
As you can imagine, that would require some serious decompression, not just from 12.0 max BR to 12.7 or something like that, but from 12.0 to 17.0 or 18.0.
