I realized we don't have a topic for a proper discussion of what future AFVs should look like, in the style of a general AFVs discussion rather than country-specific threads.
I spotted a revived potential need for future MBTs - a coaxial autocannon to replace the coaxial MG. The reason? An APS neutralizer.
Here's my short post on why I think it should happen:
I didn't add it there, but I see lasers as a potential alternative. However, I don't think they're viable because of the power required to properly neutralize an APS's components, especially if these components are dispersed, or worse yet, effectively camouflaged. An autocannon will be able to disable not only the APS but other external components all at once.
Similar to the engagement method showcased by Russia where they fired 2 Kornet missiles (almost) simultaneously to defeat an APS, a hypothetical mode of operation could include firing a burst of 2 KETF shells at a target prior to firing a main gun shell.
An additional alternative could be to use a single main gun ABM shell that would initiate outside the scope of the APS's engagement range (e.g engagement range is 30m so it initiates at 50m), but it would have 2 main issues that are a longer time to kill a target and a greater consumption of ammunition (up to a 3rd of ammo would have to be allocated to ABM munitions strictly for anti-armor operations).
