Answer:
Fragging
Desertion
Increased drug use.
Explanation:
Fragging is a term used to describe the act of unhappy soldiers who would typically use fragmentation grenades to blow up unpopular leaders (usually squad leaders to even generals) during the Vietnam War.
Desertion is typically what occurs after the loss of morale, where soldiers pretty much run away from their jobs in the military.
American troops were known to have large amounts of substance abuse, whether they bought them from the black market, received them in care packages, or they simply obtained it by their own means. Substance abuse typically affected the morale on a individual level, rather than generalized.
