Slightly off-topic: please, explain, if it possible, why modern small-caliber cannon' barrels have been frequently surrounded by extrnal structures, like on this vehicle?

These rectangular cross-section boxes, with holes in it intended to be uses kind of additional protection?

Thanks in advance!

No.  They provide extra support to prevent barrel whip.  Modern materials being what they are, to improve accuracy the thin barrel needs extra support.

Thank you, Kadija_Man!

Curiously, a classical IFV (BMP-2, Bradley, Warrior) has have a "unsupported" cannons, mounted in turret.
Why this changes in modern types?

Why the indentations on the hull side armor? What purpose could that serve being applied in the way it's applied? Part of it almost look like it's a handle, but there are also visible holes that go deeper...

Is the 35mm gun confirmed? If so is it the WOTAN 35?

I thought the Rheinmettal bid used the 30mm gun?

I'd assume they're for attaching and detaching the armour.

The need to hit pin-point targets.  Previous weapons were meant to be infantry support weapons, rather than anti-armour weapons.   That meant the weapon was intended to "spray" it's target somewhat, rather than necessarily hit something less than a metre square at 2000 metre ranges.

Sorry, you're right, I'm wrong.  It is the 30mm gun, not a 35mm gun.  My mistake.
