Yes, and the disadvantage in mobility means you will get into position later. That gives the enemy time to prepare an ambush and pre-aim for your weak areas. Or if you have to deal with two enemies, you can’t disengage after taking one down as easily as other vehicles.
M1A2 mobility is above average, with only Leclerc, Type 90 and Type 10 beating it (as they should).
5s reload on M829A2 with fast turret rotation and gun elevation is average to above average.
Adamantium turret to 75% of ammo you will face isn’t non-existant armor. Just because the Leo2A5+ and Relikt on T-80BVM/90M make their protection stronger doesn’t mean the Abrams goes down to Ariete or Leclerc level protection, it’s still above average for the tier.
Gen 1 thermals are literally a skill issue, I run around in my Expeditionary tank at 12.7 BR and have no issues. Just learn to turn them on and off when needed. That’s what IRL leopard 2 gunners do. Even then, you have the SEPs to help with that.
The M1A2 is also slightly taller than the T-80BVM and Type 99, average for NATO tank designs. Leclerc is taller and has worse protection. Only the SEP 2 messes that up with the clutter on top of the tank.
HE ammo is (artificially) made near exclusive to 125mm guns, and the USA basically doesn’t have a proper HE round in service yet for the M1A2, not really a problem exclusive to the Abrams.
Elevated engine decks and poor rearward gun depression aren’t exclusive to the Abrams either.
Pray tell what other tank combines a turret that can resist most top BR ammo, barring DM53, a 5 second reload and overall good to average characteristics?
Because it’s definitely not the Leclerc, Type 99, T-80BVM, Merkava, CR2, Type 10 or Ariete.
Abrams is completely competitive against the majority of top tier, only completely outclassed by the Leo2A7V and Strv 122.
