I would imagine the bulk of the destroyed Russian tanks are T72 & T80s. Saw a video of 3 drone hits taking out a Russian T90. 1st took out the engine, 2nd took out optics, disabling the turret. At that point the tank reparairable, but crew abandoned it. 3rd drone hit looked might have destroyed it for good.
As far as the US M1A2 Main Battle Tank, could a shaped charge from an RPG7 that these Ukranian drones have been rather crudely fitted to carry (article mentions in some cases zip ties) destroy the M1A2 SEPv3, the latest variant? I would assume it would take something like a more powerful SABOT round from a much faster & more powerful anti tank missile.
I know the US gave Ukraine newly built but older versions of the M1A2. Article from Feb last year said after year of combat 1/2 damaged or destroyed (course big difference between damaged versus destroyed). They have reactive armor for the hulls (although not our latest uranium depleted), but they hadn‘t yet at the time been upgraded with reactive armor for the less armored turrets, which is the main vulnerability to drones which tend to attack from straight above like the javelin.

Anyway, the tank isn‘t dead yet, but is adapting with anti drone tech and defensive countermeasures.
