The M-COM alarm comes from Battlefield 4, the 2013 military shooter by DICE, where M-COM stations are central objectives in Rush mode. Players often remember the alert as part of the mode's constant attack-and-defend tension. Short clips of the alarm spread through gameplay edits, soundboards and meme videos because it communicates immediate danger in under a second. It stays popular for esports-style edits and tactical jokes, much like bomb has been planted clips in other shooter communities.
