Best Firearms for Military

I think the US military is desperately relying on old firearms. The standard issue M16 rifle is seriously getting out of date, as it's almost 60 years old now. Even with all the new upgrades, it still cannot match Kalashnikov reliability and ruggedness. The same goes for the M4 and M4A1 carbines, which are just shortened versions of the M16A2 rifle. The M9 pistol (known to civilians as the Beretta 92FS) is, in my opinion, underpowered for military use. The 9mm cartridge does not have much stopping power, and Marines in Iraq and Afghanistan are reporting that it takes multiple hits with an M9 to down an enemy. The round we should be using is the .45 ACP, which is quite famous in America, and also has a lot of stopping power. The reason for that is because it is very wide, and that accounts for reports of one-shot kills with this round. The original pistol that used the .45 ACP was the Colt M1911 and M1911A1, but those guns are severely outdated, as they are almost a century old. The new design that should be used is the Glock 21, which fires .45 ACP and utilises a high-cap 13-round magazine, compared to the M1911 mag which only holds 7 rounds. Glock pistols are also renowned for their reliability and safety, using the trademark "safe action" system developed by Gaston Glock. All Glock pistols are also exceptionally light, because they use a high strength plastic body instead of a metal one. This almost beats the M9 in every aspect.

For the M16 replacement, the AK-101 is a very nice contender. It was developed by Mikhail Kalashnikov, and it was based on the AK-47, so of course it inherits the legendary reliability of the AK family. The Americans also love 5.56mm, and the AK-101 is chambered in 5.56, so it would be perfect. The only modification needed to be made would be to accept STANAG magazines.
