M 16 is a cross-century weapon. Why didn't you perform well in the jungle of Vietnam?

Because of many restrictions, such as climate. It can only be said that m 16 was really good in other places, but it was overturned on the battlefield in Vietnam.

In the Vietnam war, it was not m 16 at first. In fact, many American soldiers first used m 14 instead of m 16. M 14 was originally designed to replace other guns and facilitate soldiers to fight on the ground. However, its firepower and range are very poor, and it is very unpopular. Later, m 14 was replaced by m 16, and the performance of m 16 was much better. M 16 is light in weight, carrying small caliber ammunition, and its lethality has decreased, but it is also better than m 14. But on the battlefield in Vietnam, m 16 became a shotgun.

In fact, it is not that m 16 itself is not good, but many external reasons. M 16 performed well in the army, but after being transported to Vietnam, the army did not equip m 16 with special cleaning tools. In other words, this gun will be scrapped when it is dirty, and the chance of repairing it is relatively small. This alone is tantamount to indirectly announcing that m 16 will not have much performance on the battlefield. Secondly, at that time, in order to save materials, the headquarters ordered the ammunition to be replaced by gunpowder. If it works well, it will leave a lot of residue. Coupled with the humid environment in Vietnam, it is easy to leave things in the gun, and it is difficult to clean them up, which will affect the shooting.

So on the battlefield in Vietnam, many jokes were left. One of the most famous jokes, throw m 16 and pick up ak47. After defeating the enemy, American soldiers will immediately lose m 16 and then pick up ak47 to continue fighting. In fact, anyone with a little common sense knows that this is unlikely. Because on the battlefield, we often judge ourselves by shouts and gunshots. If we pick up the enemy's gun, it is easy to be beaten by our teammates.
