What does the acronym PSA emphasize regarding movement in combat?

The acronym PSA highlights the critical relationship between movement and fire support in a combat environment. The assertion that "movement without suppression is suicide; suppression without movement is a waste of ammo" underscores the idea that effective combat operations rely on the coordination of movement and suppressive fire.

In combat scenarios, moving without the necessary suppressive fire can expose troops to enemy fire, increasing the risk of casualties. On the other hand, providing suppression without movement means that the enemy remains aware of your position without the threat being neutralized, which can lead to ineffective use of ammunition and diminished combat effectiveness. Thus, both elements—movement and suppression—are essential components of a tactical approach to engage the enemy effectively while minimizing risks.

While the other options touch on different aspects of combat operations, they do not encapsulate the critical balance between movement and suppression as highlighted in the correct choice.
