There are various camo challenges in Modern Warfare 4 DMZ where you have to perform certain missions with your weapons. One such camo challenge for the Special tier camo skins involves getting kills while being mounted against other players. If you do not know what mounting means, then this challenge will be somewhat difficult for you initially. But, if you know the technique of mounting, then it becomes very easy for you to finish this challenge using walls/ledges or Bipod Attachment.
How To Get a Kill While Mounted Against Players

There are multiple camo challenges in Modern Warfare 4, with one of them requiring that you kill enemies while mounted. It may sound a bit confusing if you do not know about the new mounting system, but the process itself is fairly easy to understand.
While there are two sets of camo challenges – one for the Multiplayer and one for the DMZ – you still have to eliminate enemies while mounted in both modes to complete them. No additional equipment, such as a bipod or any other weapon attachment, is required to accomplish this task.
What is needed instead is the utilization of the new mounting system, where you can lean around corners and lean your gun against various surfaces for better precision. All you have to do is get close enough to a wall or similar object and use the mount function whenever the prompt appears. It should generally be activated by tapping R3 on consoles, but you can change the keybinds in the Settings Menu.
How to use Mounting
Modern Warfare 4 also comes with the mounting feature where you can place your weapon on ledges and platforms using the keybind. The pop-up message for mounting only appears in specific areas, so you need to find the perfect spot before you can use this feature. In case you are having a tough time, you can visit the Gunsmith and unlock the Bipod underbarrel attachment and use it on your chosen weapon.
Mounting will require your character to stay prone, but the upside is that this offers more stability and lesser recoil while using your weapon. If staying still is not for you, then you might need to forgo this feature altogether. Nonetheless, you still need to get the required amount of kills to unlock the Special camo as part of the camo challenge for weapons like the Han 86, M4, and the Cronen Squall, so that’s something to keep in mind.
