There is an epidemic of Tuetonic Madness loose in this post. Germany produces some nice firearms (I own an HK USPC 40). However, they are not the be-all end-all in combat weapons design. To wit:
The G-3 (and all its variants) is an OK battle rifle. It never set the world on fire except by virtue of discounted pricing to a lot of third world customers. Accuracy is so-so. Sights are merely adequate. Trigger sux. Selector ergonomics blow. My M21 shot rings around any HK G3 made when I attended the Bundeswehr Sniper Instructor Course. Ditto for the stock M14. Effective full-auto? In 7.62? Pullleeeze....The folding stock is great for Panzer Grenadier Dismounts but causes accuracy to suffer.
G36? Crappy iron sights. Fragile day optic (leaks, condensation, and fogging). Non-captive take-down pins (try and find one in the dark, in the snow, in the mud...Yeah, I have used the cute little pin storage holes).
Accuracy is good but no better than M4. M4 is a way better CQB weapon. Balance is overly front end heavy (like the G3). Bundeswehr was having some serious problems with magazine reliability and forbade their troops to fire the weapon for some months after issue. BTW, did I mention the preset factory optic zero, which, if changed by the shooter, voided the warranty and broke the gas seal on the scope. Day optic subject to fogging and freezing-up in cold or wet weather. Herr Feldwebel, Ich kann nicht meinen treffpunkt gesehen...
Now the US Army wants to buy a G36/20mm WunderGranatenWerfer combo that is as big as a SAW and weighs about as much as a BAR...Oh Boy! The weapon relies on electronics to fuze the round for detonation at appropriate ranges. A test weapon decided to arm a 20mm at muzzle distance (airburst) and damn near killed the firer and two others (including a German SGM involved in the OCIW project). To be fair, the round caused crippling wounds for all three (but wasn't actually lethal).
I can hardly wait...Make mine Colt M4, followed by the AK74 (as most recently tweaked by the Russians to accept modern combat accessories). I wouldn't feel badly armed with the G36, but it is not all it's cracked up to be (unless a new BMW is included as a carrying case!).
