How did the us military interact with afghanistan's military forces during the war inafghanistan?

The U.S. military trained them.

Explanation:

An important aspect of the United States intervention in Afghanistan was the training of soldiers. The Afghan National Army was severely deficient. It suffered from shortages and desertion. 90% of the soldiers were illiterate, and they lacked formal military training and discipline. Therefore, the U.S. military was important in providing this training.

on april 6, 1917, the u.s. joined its allies--britain, france, and russia--to fight in world war i. under the command of major general john j. pershing, more than 2 million u.s. soldiers fought on battlefields in france.
