Different tools for different problems. Abrams is specialized to do a few things amazing and the Bradley is a general purpose tool that can do many things very well. We see the Bradley succeeding because it is in the right environment with a prepared team of operators. Abrams succeed where the only thing that doesn't shoot is a camera.
It wouldn't surprise one bit me to see Ukrainian veterans training westerners on their own weapon systems when this shit is over. Their experiences will be irreplaceable.
