HK21

The is a light machine gun featured in Call of Duty: Black Ops, Call of Duty: Modern Warfare II and Call of Duty: Modern Warfare III.
==Call of Duty: Black Ops==
===Campaign===
The HK21 is the secondary starting weapon for Hudson on the level "Rebirth." It is very powerful and usually kills in one or two shots to the torso, and has the ability to gib most enemies. It can also be found in other missions, such as "Numbers" and "WMD". Rarely, it can be found with a Round Drum, which gives the player 80 rounds per drum, making for a very effective weapon. In WMD, it can be picked up from dead Soviet soldiers
===Multiplayer===
The HK21 is unlocked at Level 2 to the player, as part of the default LMG class. It is also automatically unlocked in Create-a-Class.
The HK21 by default deals forty damage at all ranges, killing in three shots, or one shot at any range in Hardcore. The HK21 does 56 damage on a headshot at any range, allowing the HK21 to get a two shot kill at any range with two headshots, or dealing up to 96 damage on a headshot-bodyshot combination, which can kill mildly injured enemies. The HK21 has high penetration power, allowing it to retain most of its damage when shooting through obstructions.
The HK21 fires fully automatically, with a rate of fire of 750 RPM.
The HK21 has recoil values of 70 to the left, 70 to the right, 60 upwards, and 40 downwards. The HK21 has a centerspeed value of 1700.
The HK21 restricts users to move at 87.5% of the base movement speed, or strafe at 40% of the base movement speed. The HK21 allows users to aim down the sights in 350 milliseconds. The HK21's hip-fire spread is average. The HK21's reload animation is 3.75 seconds long, or 4.75 seconds long on an empty magazine. In either case, the user can Reload Cancel after 2.9 seconds. 
The HK21 has a magazine capacity of thirty rounds. The HK21 has a starting ammo loadout of 120 rounds.
The HK21 has the standard assortment of LMG attachments to choose from. All attachments work as expected on the HK21, with no signifciant difference in effect when said attachments are used on the HK21.

===Zombies===
The HK21 can be found in Zombies mode and can only be obtained from the Mystery Box. It starts with a magazine size of 125 rounds and with an extra 500 rounds. It has a reduced rate of fire from Multiplayer, firing at a measly 535 RPM, making it very unforgiving in this regard. However, the high amount of ammunition at disposal, and the low rate of fire, make reloads few and far in between. That being said, however, reloads can be painfully long, usually tempting the player to buy the expensive Speed Cola. Double Tap Root Beer is extremely useful on this weapon, as the large magazine will still take a long time to deplete, despite the great increase in the rate of fire. However, Double Tap Root Beer is absent on Ascension. The HK21 is often viewed as a "Love it or hate it" style weapon. Some players will love the high magazine size and power; however, others can simply detest the handling of the weapon, particularly the ADS time, reload times, and movement speeds, alongside the extremely slow rate of fire.
When Pack-a-Punched, it becomes the "H115 Oscillator". The magazine capacity is increased to 150 rounds, and the maximum reserve ammunition is increased substantially to 750 rounds, effectively leaving 900 rounds to be used as soon as it's obtained. The damage gets an increase as well. However, the maximum bullet damage of 210 is definitely less forgiving than other weapons, coupled with the excruciatingly low rate of fire; however, the high amount of ammunition offsets this.
In terms of performance, it is often compared to the RPK, due to their extremely large magazine capacities, and LMG statistics. The RPK is generally better when damage is concerned, as the much healthier rate of fire will often prove to down zombies quicker than the HK21 is capable of. However, the HK21 has overall better ammo conservation, and it has a much larger reserve supply. However, both of these weapons have little ammo consumption concerns, barring when the RPK user is using Double Tap Root Beer. Generally, many players will prefer the RPK over the HK21, for the higher damage, in trade for less ammunition, which it packs plenty of.
