Several factors:
The Bradleys Ukraine got were M2A2-ODS-SA. Which means many improvements from Desert Storm/OIF learnings and newer tech. Including:
- 100 HP increase (20%) in the Cummins diesel
- Improved armor (lost the stupid firing ports, etc)
- Improved electronics including satnav, blue force trackers, etc
The A3 and A4 models used by US has even more HP, additional electronics, etc.
My IN son went heavy after his para time as LT, and commanded a Bradley company for his CPT time. Big improvements, and they joke about the Bradley myths from Desert Storm & OIF as they are much improved. The A3 and A4 mainly added the independent cupola viewer for the commander, but also even more HP.
One of the myths was range/speed relative to the Abrahams tanks. Even the A2 has much further range now, and the A3/A4’s even more speed. (The A2 lost top speed, but gained torque offroad and-acceleration). A2-ODS also got the newer transmission as part of the ODS upgrade.
So now US logistics planning is done around the M1’s as the Bradleys have double or more the range offroad or during road march. Just the difference between diesels and turbines. Even the current M1’s with APU’s still need fuel more frequently
Chain gun is still quite effective, high rate of fire and can instantly switch between AP and HE rounds. Not a tank main gun, but does have many tank kills. (think Sherman vs Tiger/Panther)
The “SA” improvement is essentially the electronics/data bus from the A3, as well as the improved fire suppression. Laser targeting, blueforce/tac nav.
No, they are not tanks. But can hold their own against soviet era armor which is most of what they are encountering in UKR as long as they are well fought. Which by all inclinations the UKR forces seem to be adept at.
Much less maintenance, the Cummins are tried and true reliable powerplants. I could see how it might be more maintainable for them than the M1’s. Their favorite AFV is the swedish CV-90 apc. And it has the best stats in terms of survivability.
All of this is public info, just worth mentioning as many are familiar with the original Bradley. Probably the biggest current complaint is capacity, it creates a smaller IN squad than they prefer.
