Breeze is a very large map, so most gunfights will be long range. The best weapons for this map are the Vandal, Guardian, Operator, Marshall, and Sheriff. This makes the map harder for new players.
Viper and Harbor are considered the best smoke agents for Breeze. Their wall smokes cover the most angles due to the large map size.
Always be careful for an enemy lurking up mid halls. It's best to place a trip there for information since enemies will sneak up often.
If the bomb site is contested, try to plant the spike behind cover, usually this will make post plant harder. But if you have the site, plant the bomb in areas where you can see the spike from multiple angles.
Late post plant wraps from spawn to mid can actually be very strong. Just be careful for the enemies rotating through mid.
