Nowhere did I imply the Type 60 should go lower, but if it did that wouldn’t be a problem since it’s also a terrible vehicle. You can’t slap ATGMs on a bad platform and have it magically perform well:
Armour: It has none. It can and will be penetrated frontally by heavy machine guns in the blink of an eye, and even rifle-calibre machine guns can get through the sides. If an artillery shell or bomb lands in it’s adjacent postcode, it dies.
Survivability: It has none. Despite being so big it only has 3 crew and they’re all clustered in the front. So not only can everything penetrate the armour from any range and angle, but every penetration is an almost guaranteed one-shot kill. In addition the thing is the size of a double-decker bus, so you can’t even hide it to avoid instant death, nor can you bait people into shooting the “empty” rear end because that’s where all your ATGMs are. Oh it’s also in a painfully obvious desert camo at all times.
Mobility: Decent for a light tank. Sure the on-paper top speed is great but you’ll realistically never achieve that in a match, it’s fast but not significantly faster than any other light tank in the BR range. It’s reverse speed on the other hand is complete piss, it steers like a brick and the wheels mean you’re barely faster than a Maus in deep snow, sand or mud. It goes fast in a straight line but good luck doing literally anything else with it.
Firepower: Mediocre. The unstabilized 20mm is decent against light tanks and low-flying aircraft but is worthless against anything else. The ATGM is good but it’s an early ATGM at 6.7, so 75% of your targets are heavy tanks that can easily eat the damage from 2 or 3 missiles, and thanks to the size of the vehicle you’ll basically never find a spot to launch the missile whilst hull-down. You just have to sit there in the open, in a vehicle the size of a TOG with wet paper towels for armour, slowly guiding your missile at a target that can fire back with at you with an AP round 5x faster than the MILAN that’s guaranteed to kill you whilst your missile might kill a third of their crew.
The Marder might have fewer missiles but it gets good armour, can actually survive penetrations thanks to the front-engine, has better all-terrain mobility plus neutral steer and a significantly better reverse speed, and it’s 20mm gets far better depression/elevation angles with an LRF. Outside of ATGM count and on-paper top speed it’s better than the Ratel 20 in every single category by a wide margin.
The Wiesel gets no ATGMs and also has awful armour and survivability, but has the same improvements to the 20mm as the Marder in addition to APDS and Gen 2 thermals, plus it’s faster than the Ratel and it’s tiny. A Wiesel on the flanks can rapidly do more damage to an enemy team than a Ratel could ever dream of before completely vanishing whilst keeping every enemy consistently scouted the entire match.
