.308 Subsonic

.308 Subsonic (olive) is an Ammunition type in Surviv.io. It is only used for the AWM-S, a high-powered sniper rifle added into the game in the v0.5.0 "" update on July 26, 2018.

There are no other weapons in the game that use the .308 Subsonic, although there may be more in the future. The .308 Subsonic only spawns with the AWM-S or rarely in Large Ammo Crates.

Trivia

 * For a limited time, the .308 Subsonic was known as the ".300 Subsonic".
 * This is the rarest type of ammunition in the game.
 * As such, it is the third type of ammunition that is only used for one weapon, alongside the .50 AE, which is used for the DEagle 50 and Flares which are used for the Flare Gun.
 * .308 Subsonic bullets are muted green in color.
 * Due to this, this projectile can be very hard to spot in the Halloween Map.
 * It is possible to get .308 Subsonic from a Large Ammo Crate with a Wood Axe, but this is rare.
 * The ammunition is the second ammunition to have a green shade, the other being 5.56mm. There is a difference in hue between the two, ensuring that players would not mix up the two.
 * However, due to its dark shade, the ammunition looks very similar to the aforementioned .50 AE cartridge, and thus, players may mistake the two for each other.
 * The cartridge most likely represents the .308 Winchester cartridge. Although the real-life AWM does not use that cartridge, the AWC (which the in-game AWM-S was based on) does use the cartridge. The name of the ammunition implies that the round is a special "subsonic" round; a round that travels below the speed of sound, much quieter than most bullets due to the lack of a sonic boom. This is actually reflected in-game, as the AWM-S has the slowest bullet speed of all the sniper rifles.
 * The ammunition's ID is 308sub.
 * Technically, when written in metric, the .308 Subsonic would translate to 7.62mm.
 * This ammo is manufactured by Winchester, the same maker for some guns in the game, including the Model 94.
