Trivia

Many Sergeants in the games are shown wearing caps instead of the CH252 helmet their subordinates wear. While wearing this cap is useful for identification, it should cost the Sergeants the loss of their Heads-up display, making aiming and long distance communication more difficult. How Sergeants who wear a cap get around this setback is never explained.
