How did the weapons used by the frontiersmen in the patriot army give them an advantage over the well trained british army?

The weapons were handled in a professional manner, in addition to being supplied and replaced by the French government.

Explanation:

The weapons were financed by the French government, in addition, France sent men experienced in the use of these weapons to fight and teach Americans to use them. Thus, we can say that the great advantage of these weapons is that, because they are financed, they were replaced whenever necessary, in addition to having experienced and incisive manipulators in battle, it is estimated that France sent about 7500 men to work in the continental army. This gave the continental army a lot of advantage.
