IMR

"Four round burst. Prints rounds to ammo reserve. Best in class damage."

- In-game description.

The IMR (Integrated Munitions Rifle), referred to as himar in the game files, is a four-round burst (fully-automatic in the campaign) assault rifle in Call of Duty: Advanced Warfare.

Campaign
The IMR is a starting weapon in the first level "Induction", and is one of the main weapons used by the Atlas Corporation. However, when they are enemies, they only use it in the PC and next-gen versions of the game. Unlike its multiplayer counterpart, the IMR is fully automatic in campaign, and prints 30 rounds to reserve every 30 seconds.

Multiplayer
The IMR is unlocked at level 32.

Despite the in-game description, the IMR has medium damage per shot. It requires all four shots of a burst to hit at close range, regardless of shot placement. This damage profile is retained out until long ranges, where five hits, and thus a second burst, may be necessary. Headshots seem to have no beneficial effects. The rate of fire is high, the burst delay is short. Recoil is extremely low, rendering the foregrip almost ineffectual.

The IMR has a 36 round magazine, allowing for nine bursts before a reload. Using Extended Mags boosts the capacity to 54 rounds, but comes with a downside: 54 is not divisible by four, only making 13 whole bursts and one two-round burst, similarly to the M8A1 with Extended Mags from Black Ops II. Due to its 3D printing technology, four extra bullets are added to the reserve ammo every five seconds. The IMR has a long reload time, which makes it advisable to use the perk Fast Hands or use Extended Mags. However, the IMR has an exceptional Reload Cancel time, making it very useful to players who are capable of doing so correctly.

The front iron sights are rather clear despite the rather large hind sights. Optics are useful for medium to long range engagements, but they are not necessary; investing in a different attachment may instead be more beneficial. Overall, the IMR is a good choice for medium range engagements. It has strengths in the form of a fast rate of fire, great accuracy, good amounts of ammunition, and a fast reload cancel time. This is a great weapon to use for a more experienced player that is aware of factors such as burst delay and reload canceling.

Exo Zombies
The IMR appears in Exo Zombies. It is available via the 3D Printer. Due to the IMR being able to print out its own ammo, it is an extremely good weapon and almost a must-have if players intends to reach high rounds.

Trivia

 * The gun's 3D model when held by the operator has a substantially shorter stock than the image in create-a-class.
 * Additionally, the IMRs seen in the armory's showcase in the campaign mission "Atlas" have a much shorter barrel than usual.
 * The IMR was originally called the HIMAR in early development.
 * The idle animation in first person always assumes the position of holding a foregrip (although this is difficult to notice, since it isn't grasped like other foregrips), even if the weapon doesn't have one.
 * In the mission Induction, the IMR has a unique model, with a different red dot sight and a white finish. This variant can also be found in other levels later in the game.
 * The 3D printer on the side of the IMR is marked "Formcaster 3D", although this is very hard to see on the default IMR. It is more noticeable on other variants.
 * The IMR seems to use a 3D fabricator (Formcaster 3D) to create ammo from a liquid matter source (visible in the stock).
