Comparison with analogues
- M36 (90 mm) - American variant of the cannon, which the BK90 was derived from. Though it does not have the BK90's HESH round, it has a large variety of AP rounds for use.
Usage in battles
The BK90 with HEAT-FS is a formidable opponent on the battlefield that can penetrate every 6.7 tank's frontal armour at any range. It is best used in hit-n-run types of attack due to the vehicles it is mounted on.
Pros and cons
Pros:
- Access to HEATFS that can penetrate every tank that it typically has to face
Cons:
- Limited kinetic ammunition variety - the only kinetic ammunition is APCR
- Of the chemical rounds available, only the HEAT-FS round is of noteworthy use
