From what I’ve read, all the M1s over there are M1A1 SA spec at least, with many having upgrades beyond that.
The Bradley is probably more of a success because it lends itself well to the tactics used by former BMP and BTR commanders. They also seem to be employed in pairs in areas of elevated threat as opposed to just solo, as one Russian T-90 crew recently found out to their cost.
Wise use of equipment.
