What can hinder the effectiveness of "plunging fire"?

The effectiveness of "plunging fire," which involves firing at a steep angle to maximize the impact on a target, can be significantly hindered by obstructions in the line of fire. When obstacles exist, they can block or deflect the trajectory of the rounds, preventing them from reaching their intended target and potentially causing the rounds to malfunction. This makes it crucial for operators to ensure a clear line of sight and a free path for the rounds when employing this tactic.

While the other factors, such as distance to targets or the speed of moving targets, can impact tactical decision-making, the direct interference caused by physical obstructions is a more fundamental limitation that can compromise the capability to effectively utilize plunging fire.
