-> The 100mm will provide the air blast of 14.7x 40mm going off at once, making it far more likely to be able to collapse a room/ building / fortification.

True.
But it is very unlikely that a field fortification or bunker will be collapsed by under 2 kg going on its outside. Field fortifications and bunkers are designed to withstand overpressure. This is why BDM work by penetrating into the bunker and going off in the inside. Either by KE or by tandem warhead designs.

Civillian structures on the other hand have a good chance of being collapsed or at the very least seriously damaged. Which IMHO is part of the problem. It makes such ammo dangerous to use. Unless you are very sure that there are no civillians left in the structure and no friendlies allready have entered or are close by you can not safely use such ammo.

Time fused ammo for ACs does the trick of penetrating into a bunker or structure and going off inside mostly causing effect against the occupants and not the structure itself. Which IMHO makes it far more effective in this role.

Will be intresting to see if it materialises and if it does how well executed.

Thats an interesting development, but makes sense as a lighter tank may be needed to get up to the very austere areas in the Himalayas where they are squaring off against China

Not only China. Pakistan as well.
For India such a AFV makes a lot of sense. Limited resources and infrastructure. It also will most likely not face 3rd gen or later MBTs so the 105 is a very sensible choice to duel with its kin.
Allthough the ATGM plus AC combo would work for it as well.

Nice find. The 105mm AMP seems further confirmed from this slide, or at least more 105mm development.

I am wondering about the Lynx FSV in this context. Is there a fundamental difference between it (or other FSVs) and modern light tanks?

I'm not sure; it certainly looks like what I'd imagine a Light Tank would look like. Hell of a lot cooler then the 105mm MPF thats for sure.

An FSV like the KF41 Lynx is an IFV that has been fitted with a tank main gun.  Having been designed to carry infantry, it has a front engine and very tall hull.

A light tank like the M8 Buford is designed solely for the single purpose of armored gun platform.  The engine is in the rear and the hull is noticeably less tall.

aaah, thanks! So if one wanted to maintain family advantages in logistics but wanted an actual tank hull, you'd take the chassi and drivetrain and other tech and stuff it into a new hull with the disred turret I would think?

Sounds about right.
