Watch the documentary Restrepo. It is enlightening to say the least. I am not an expert on small-unit tactics, but this is obvious incompetence and poor training. First the ROTC officer sets a stupid and useless objective of establish a base outside their base for no apparent reason at all. Then the soldiers, while carrying out this pointless exercise, receive a few pot shots here and there from literal goat herders. They respond by panic firing blindly into the night at invisible targets hundreds of meters away. No fire control whatsoever: no direction from superiors; no attempts to acquire targets; no engagement priorities; no restrictive fire zone; nothing. By the end of the documentary, after they had been in country for 6 months or so, they begin to demonstrate some minor levels of fire control and unit cohesion, making some efforts to identify targets and so forth. But for months, they are rabble, not professional soldiers.
