Maybe

A brand new M1A1 isn't exactly the very definition of a pile of shit, but maybe here that's just political posturing and they're mostly sending junk/"second-hand-broken-toys" with a joke training attached to it idk

But as Foreign Policy has pointed out, the tanks aren't really what Kiev is currently after. What wasn't approved are long-range missiles being discussed by the Biden administration, specifically the Army's ATACMS missiles.

Also they require a steady supply of fuel, the abrams sucks a fuckton of fuel per hour, they can only last something like 24h without refueling after that they're sitting ducks, it's its main weak point, it's the battle tank of the US, it requires the US with infinite fuel/money behind it, it uses jetfuel...

>Fuel capacity 504.4 US gallons (1,909 L) ... The gas turbine propulsion system has proven quite reliable in practice and combat, but its high fuel consumption is a serious logistic problem.[133] The engine burns more than 1.67 US gallons per mile (392 Liters/100 km) or (60 US gallons (230 L) per hour) when traveling cross-country and 10 US gallons (38 L) per hour when idle.[citation needed]

504.4/60=8.4

The thing has an autonomy of less than 24 hours, roughly

48h if it remains mostly idle
