I want to give some clarifications on the G-11.
orc4hire, that weapon works - the only thing that they couldn't manage was full-auto with a 50 round clip. They couldn't find out why the weapon jammed between the last ten shots on many trials. So they just cut the clip to have only 40 rounds
and full auto works fine.
And Arralen, the Bundeswehr didn't supplied that weapon not because it is expensive but it's unusual ammo; Germany as part of the NATO uses only munition that every other member of the NATO can use (the 120mm tank gun in the M1 Abrahams is the same as the French LeÇlerk and German Leopard 2, the 155m artillery ammo can be used by every member and so on down to the infantry weapons). To have a weapon that uses completely different ammo would put additional logistic problems to combined actions.
And the discussion over 'radical' improvement...
So you said that upgrading from smoth bore to rifled bore was radical ... (so the new smoth bore 120mm cannon is a fallback ?? just joking).
The G-11 uses an octagonal bore that way the bullet doesn't loose as much energy as a bullet looses in a rifled bore.
Caseless ammo is IMHO as radical as improving from powder and ball loaded guns to cartridge loaded.
The ammo is much lighter so a soldier can carry three times the ammo. No need to hide/pickup the cartridge cases in covered ops - there is no trace that a soldier was there and fired a weapon. No hot cases that might hit you or another squadmember.
There is no need to have a clip and fill it by hand - the clip for the G-11 carries 80 rounds (2 x 40) and the empty clip is very leightweight in comparision with clips for the G-3, not even mentioning an empty 50-round MG belt...; so the ammo is always distributed clipwise and not a box with loose cartridges.
The weapon itself is KISS - keep it simple stupid - meaning the whole fire mechanism is enclosed and no objects can get into it nor can the soldier open the mechanism and by accident break it. The weapon is very reliable and even mud wont really hurt the weapon.
Another thing is that the weapon is 'self cleaning' - for all who served for one or another army, remember the weapon cleaning after firing the weapon; the G-11 doesn't need that - each shot will make sure that it bore and mechanism gets a cleaning gas blow.
The short and lightweight overall design is well balanced - it is short and light enough to not hinder the soldier - on the other hand long and heavy enough to have a good and accurate hold on the weapon itself.
Together with the build in scope and the accuracy of the weapon in single and burst mode it is IMHO a radical improved weapon.
