Final answer:
The South Vietnamese army faced various problems after the Paris Peace Accords, such as being spread thin, high desertion rates, lack of air support, scarce ammunition, an outbreak of disease, and poor training.
Step-by-step explanation:
After the Paris Peace Accords, the South Vietnamese army faced several problems. Firstly, the troops were spread thin and many areas were left vulnerable due to insufficient manpower. Desertions reached an all-time high, which further weakened the army and reduced their effectiveness. Additionally, they had very little air support, making it difficult to carry out operations effectively. Ammunition was scarce, leading to supply issues and limited firepower. There was also an outbreak of disease, which further impacted the health and capabilities of the troops. Lastly, a significant issue was that most of them were poorly trained, making them ill-prepared for combat.
