Such a bugger the Russians took one look at the 40mm wundergat 'able to defeat previous generation MBT's' and issued a load of extra 100mm & 125mm, and both have tube launched ATGM's, armed light tanks to its rapid reaction forces.
40mm CTA vs the same 125mm gun as fitted to a T-90 MBT? Sounds like a fair fight
Not sure youre making the argument you think you are
Russia has stuck onto a light AFV a bfo gun - which will chew up AJAX
AJAX has the 40mm which is more than sufficient to chew up those BFO armed light armoured Russki AFVs
From this youve concluded AJAX is undergunned and vulnerable because its dead if its hit by 125mm - but youve ignored that the Russki is dead to Ajax 40mm
From this it could be equally valid* to conclude that Ajax is the dogs danglies - because the Russkies have been forced to massively up gun their light AFVs to counter it. As such they carry less Ammo and its also heavirr and bulkier to transport.
So a win for strike then as theyve already degraded the enemies ability to fight by complicating logistics before they start.
I suppose in keeping with your standards I should make some unsubstantiated remark about needing a tank gun because they cant make a decent auto cannon .
*And equally lacking in context but you started the this specific case thing.
