Why this hullabaloo about G36?
Mostly because of politics. The reports about the G36 issues appeared just before the elections in 2013. The German ministry of defence has suffered a lot of troubles during the previous period of rule by de Maiziere (now ex-defence minister) and his predecessors.
In mid to late 2013 a number of articles has been published about the troubles associated with the "latest" military acquistions: the problems of the Puma IFV, UHT Tiger, K130, Euro Hawk and finally the G36.
The Euro Hawk is the only real failure: The whole program costed more than 1.3 billion Euros, but then in 2013 it was publically disclosed, that it failed German and EU security trials and hence was not allowed to fly anywhere close to inhabited areas.
The final result of the official investigation also didn't found the G36 to be the fault of the reported troubles, but the ammunition from on of the manufacturers:
Sturmgewehr G36: Mangel-Munition soll Probleme verursacht haben - SPIEGEL ONLINE (newspaper article speaking about the results of the official investigation)
The G36 can have trouble with overheating (i.e. the plastic starts to melt once the barrel gets too hot), but this should never happen in combat, unless the user fires an extremely high amount of ammunition without any firing pause.
They could have simply taken FN-FALs and AKMs with them to Afghanistan.
And why should they take the FN FAL or AKM with them? The AKM is worse in pretty much all regards when compared to the G36. The FN FAL is not in German service, but it is very closely related to the G3.
The German solution (which has been ignored by the media reporting about the G36 issues) was introducing two further versions of the G3 (the G3 ZF and G3 DMR) and the G28 (a version of the HK MR 308) into service. All of these weapons are chambered in the older 7.62 mm NATO round.
According to offical German sources, the G3 is considered to be accurate enough for effective engagement of enemy forces up to 600 m, while the G28 has an effective range of up to 800 m.
No Dear, I am very sure German servicemen are very professional and they know how to keep there firearm operational ..
And its the barrel here in question not the Rifle as whole, A common 18inch barrel of any rifle is more or less same except the metallurgy ..
I am not making up any facts. The lmG36 was a special version of the G36 with bipod and a heavier barrel. The barrel was thicker, which means that it takes longer for it too reach the critical melting point of the plastic, and that it had more surface to dispense the heat generated from firing.
The lmG36 however was never accepted by the German army, because it was considered to be expensive and to be an assault rifle (despite being called "light machine gun 36" by the manufacturer), the reason for this being the lack of quick-barrel-replacing mechanism.
The Germans might be professional servicemen, but if you spoke any German you should visit some of the more professional German websites or speak to actual German soldiers. There are quite a few "horror stories" about the some members of the German army or some decisions made in the past by the DoD.
PS: Can somebody tell me why the forum is broke? It is really hard to distinguish quotes from the rest of a reply, because the stylesheet (?) of the forum is missing.
