Object 430
Ok, not the most out there, but in fairness no Tier 10 really is that unpopular or terrible, though the 430 is certainly the least popular one out there.
The main reason isn’t really down to the Object 430 being completely and utterly dreadful, it’s actually not too bad. It’s more the fact that, compared to the T-62A or Object 140, it doesn’t have too much of a purpose. It gains weird hull armor that still doesn’t work too well, and an irrelevant DPM advantage over its competitors. As a trade-off, it takes a significant hit to gun handling, which is one of the Russian Medium’s main strengths. This also reduces the Tank’s effective DPM as it’s forced to stop and aim for longer, or miss more shots.
Regardless, the Object 430 is pretty fun to mess around in once every now and then and certainly isn’t a bad tank by any means. That just about sums up my list for the 5 Tanks Players Are Shocked to See in Battle. Which Tanks do you find most shocking when you see them?
