One of the really tedious things about this forum is the need for americans to argue in bad faith. The M30 is a howitzer and it was used to defend Afghan bases with cannister, so either you were ignorant and too lazy to look it up or did know and decided that you would ignore the thread history to be a disingenuous Stan-like shitstain. 

This is the only  forum in which I've ever seen the "You are arguing in bad faith!" complaint, which has only been made by a few members who are somewhat less than rational.

Insulting a fellow member by calling him a "shitstain" would seem to meet one of the "bad faith" definitions on the web.  to argue in bad faith - Google Search

And speaking of being ignorant, do you know what are the search results from googling "M30" ?  m30 - Google Search

As for ignoring the thread history, until your comment above, there had not been a single post in this thread about howitzers.

I suggest looking at Serbian combat experience for possible reasons. Perhaps there have been lots of materiel targets in recent Serb wars?

IIRC One of the reasons for the Croatians to develop this 20mm beauty during the 90's was to target the nightvision gear on Serbian tanks.  So the Serbs have some experience being on the receving end of 20mm AMRs,

Gun action is very much classic  It's Hispano-Suiza HS.804 (which was manufactured in Yugoslavia under licence), so a derivtive of pre-WW2 HS.404.

A lot of old target scopes were mounted in a way that a spring returned them to position

the old 50 caliber multiple projectile round from Vietnam for Riverine units would probably be better than any "Cannister round" in a .50.

The Army seems to agree; they are playing around with bringing Duplex / Multiplex rounds back for .50 BMG.

ARDEC have developed a .50 calibre full-bore duplex round, the XM1175 ‘Interceptor’, this round was designed to be used in all existing M2 heavy machine guns. This means the new ammunition could be used in vehicle mounted M2s or in perimeter defence, in theory any M2, deployed on land, sea or air, could utilise the round.

One of the advantages of the new round is that it can be employed in situations where collateral damage is an issue. The lower mass and the nature of the XM1175’s aeroballistics means that the round will decelerate more rapidly and cause less damage to objects it hits, creating what ARDEC describe as a Smaller Surface Danger Zone (SDZ), giving troops more engagement opportunities in closer quarters.

Parisi explained that “while the technology we have developed is caliber-agnostic, most of our work has been in caliber .50 due to widespread use of the M2 machine gun and the suitability of the two systems for the given mission set.” ARDEC hope the XM1175 will see service in the near future, but in the meantime they are continuing development of small caliber multiplex technology.

I wonder if it will function in a gau-19?   If there is ever a situation where truly Massive amounts of projectiles are needed...    mini Phalanx?

Does the 50 really create a large danger space for troops.....this would make a strong case for a 357 cheytac or 338

Salvo sounds simple enough till you do the  propulsion around the corner and fire trough 3 barrels

Only if you're going to load the 357 or 338 with ultra-lightweight, low-BC bullets that lose velocity very quickly.
