What I know (because I've been standing on one..) is, that the turret is a Swiss made thing and the thickness of the armor, well, that you won't find out except you buy one...
Even the German A5 is a modification of the A4 there are only a few new built A5 the rest are refitted A4 (as far I know from talking to other army members...).
The armor can be even altered with extra plates... so, yes it is still the latest A4 model but with extra armor, a different turret and gun and absolutely not the same as the German A4 or A5 or A6.
The Picture therefore could be still lbm4403. Both the icons (1416 and 1418) are actually wrong, because the back of the Swiss Leo2 looks completely different - they have an extra muffler(?). So I just left the lbm and the Icon because they look cooler
I like it how it is. The armor is not that different to the German version and for the game play it doesn't really matter. Does it?
