What is a potential consequence of using tracer rounds with the M240?

Using tracer rounds with the M240 can indeed create visibility issues. Tracer rounds are designed to produce a bright, visible trail as they travel through the air, allowing gunners to see the trajectory of their shots. However, this visibility can be a double-edged sword. While tracers help a shooter adjust their aim, they also signal the shooter's position to the enemy. In a combat environment, this can make the shooter a target for enemy fire. Additionally, in certain lighting conditions or environments, the bright glow of tracer rounds can create distractions or impair visibility for both the shooter and allied forces. Therefore, while they have their benefits, the use of tracer rounds must be weighed carefully against the potential for unintended consequences related to visibility.
