Destroyed tanks counted as "air victories" in April, 1945 by German fighters in east

[Boomerang]

It does seem quite reasonable that 20 mm fire could disable, as opposed to knock out a tank via a fortuitous hit to, for example, a track link.

IMHO another possibility to consider in this discussion is that a fighter could strafe and destroy a half-track, or similar weakly armoured tracked AFV, but claim a tank destroyed. Unfortunately this is moving towards speculation that cannot be tested with hard information, so it can't really go much further.
