From Halopedia, the Halo wiki
Team SWAT is a Halo 2, Halo 3, Halo: Reach, Halo 4, Halo 2: Anniversary and Halo 5: Guardians multiplayer matchmaking gametype. As of May 2008, Team SWAT is a ranked playlist in Halo 3, after being featured in two Double EXP Weekend playlists. The player has no shields, no motion tracker, and spawns with a precision weapon. Common starting weapons are the Battle Rifle, Covenant Carbine, DMR, and an M6 Series handgun. Mongoose ATVs can be found on maps such as Snowbound and Isolation. Inexperienced players should avoid this playlist as it can be particularly frustrating if they are not used to fast-paced gameplay. On October 5, 2010, Team SWAT became an official playlist in Halo: Reach multiplayer. SWAT is included as a built-in on-disc Slayer variant in both Halo: Reach and Halo 4.
The lack of shields can significantly increase the speed of the game due to almost instantaneous kills, though there is often a tendency for people to be more cautious due to this vulnerability. Head shots are crucial, as they will take down one, or in some cases with the Battle Rifle, two or three opponents with a single burst.
The SWAT game playlist features mostly Slayer gametypes although it also has some objective games in it like CTF. SWAT gametypes are standard (Battle Rifle and Pistols), SWAT pistols, and SWAT Carbines, however SWAT Carbines is only available for Ascension, Midship, and Warlock. Preferred maps:
Team SWAT was originally a Double EXP Weekend playlist, but is now a permanent, ranked playlist. It was under the Hardcore playlists group in the matchmaking menu, but, as of August 4, 2009, it has been moved to the Ranked Playlist with the other Hardcore Playlists, while the Hardcore Playlist itself has been retired.All DLC is required to play this playlist. Originally, it was Team SWAT and SWAT Magnums, but it has been expanded in the June Update to include ShWATguns, SWAT 2 Flag, and SWATBall. Unlike Halo 2, Halo 3 SWAT does not feature the SWAT Carbines gametype as it is not featured as a starting weapon due to a coding error. Carbines have since been added to standard maps as a secondary weapon for players.
Changes to Team SWAT in the June Update
The Team SWAT playlist, along with the other Hardcore playlists, were moved the Ranked Playlists while the Hardcore Playlist was retired as of August 4, 2009.
Changes to Team SWAT on September 16, 2008
Team SWAT in Halo: Reach is very similar to the previous games, the player spawns with no shields or motion tracker, and an M6G Magnum sidearm. However, the player now spawns with a DMR as their primary weapon. The Needle Rifle has not made any appearence in Team SWAT, being as it has less recoil, a smaller reticule, more ammunition, and the ability to kill in 3 shots. The only Armor Ability available is Sprint. Gametypes such as SWAT Magnums, or SWAT Stockpile are in Halo Reach. A SWAT-specific playlist was established October 5, 2010.
The announcer now says "SWAT" at the start of a SWAT game.
SWAT appears much the same as it did in Reach. Though it received its own playlist on November 12, 2012, SWAT is considered a Slayer variant in Waypoint statistics, and works to advance Slayer commendations. Players have a choice of two loadouts featuring either the BR85 Battle Rifle or M395 DMR. The secondary weapon is always the M6H Magnum. All weapons kill with a single headshot. The Magnum and DMR both kill with 3 body shots, while the Battle Rifle, due to its higher rate of fire, takes 7.
A standard game is 4v4 with a score to win of 600 points (60 kills). Damage resistance is set to .8 (or 80% of normal).
Halo 5: Guardians
SWAT has been an official playlist since the Halo 5: Guardians launch.
