M4A1-S

Overview
The M4A1-S is an assault rifle of unknown origin, presumably the Resistance. It appears to be the well known M4A1 carbine, but with a large holographic sight mounted on the top, as well as an effective, durable suppressor attached to the barrel, hence the 'S' at the end of its name.

The M4A1-S is a versatile and powerful weapon, having a selective fire mode that can switch between fully and semi-automatic, as well as having effective sights thanks to the large holographic sight attached to the top. The attached suppressor also muffles the user's shots, making them difficult to detect.

Acquisition
The M4A1-S can be found in Sandtraps, inside of a large, three-floored house, oddly locked inside the chimney, which can be reached through an opening in either the third or second floor.

If it is missed there, it cannot be found again.

Advantages
-Moderately powerful.

-Decently high fire rate.

-Quiet, thanks to it's suppressor.

-Clear and effective iron sights.

-Decently sized magazine of 30 rounds.

-Controllable recoil.

-Accurate.

Disadvantages
-Can only be found once.

-Recoil increases and accuracy diminishes if fired fully automatically, as with all assault rifles.

-Uses the somewhat scarce rifle ammo. (somewhat mitigated later on as enemies with the OICW and AK-47, which use the same ammo, begin spawning more often)

Tactics
-As with most rifles, it's recommended not to fire too fast, or the accuracy and recoil will suffer rather noticeably. Fire slowly to retain accuracy, or switch to the semi-automatic fire mode.

-If you're careful, the M4A1-S can be used to pick off enemies quietly, due to it's suppressor mitigating a lot of sounsd. Try to hide and fire carefully to pick off your targets with it.

-If you have to fire fully automatically, try carefully pulling down on the mouse while firing to resist against the recoil.

-While the reload isn't too slow, it isn't the fastest either. Be sure to reload frequently and hide while doing so. You don't want to be caught with your pants down.

-In the earlier levels, try not to use the M4A1-S too often, as rifle ammo isn't very common. In later levels, however, such as Nova Prospekt, the ammo begins appearing noticeably more often thanks to the weapons enemies are carrying at those points, such as the aforementioned OICW and AK-47.
