And if you listen to the announcers throughout the game, they can alert you when an enemy is approaching - although sometimes a bit too late to react, which isn't very funny...
Also, if you're playing on an inside map - you can actually hear the boots and footfalls of soldiers approaching - I can usually only hear that when I'm using headphones
Remember to check your scanner, too. It’s amazing how few people check it for heroes, and infiltration is amazing for scouting as well as the binoculars.
Try to use the right weapon for the map but if you know the playstyle you can make really any weapon work. (ex;heavy with lt50 is up close and person with explosives to hold the enemy at bay while the bombs are arming when attacking as resistance on S.B)
