The Haksan School Armory in Call of Duty: Modern Warfare 4 DMZ is a locked classroom inside the school building at Deadtown, a LOW threat point of interest. Behind its red door is a room stacked with weapon cases, lockers and 3D printing materials, and one of its lockers can hold a key for a different vault in another part of the map.
Quick answer: In Deadtown (map columns B/C, rows 6/7), follow the red-railed walkway beside the teal-and-white tiled school wall to the red wooden door, then use “HAKSAN SCHOOL ARMORY – UNLOCK” with the key.

Counting Room Vault key in the Haksan School Armory
One of the Military Lockers along the armory wall held a COUNTING ROOM VAULT key, an EPIC key with a value of 100. Its card reads “F4 – Unlocks the counting room’s vault on the main floor of the Heavenly Luck Casino within Cheongun Village.”
That makes the Haksan School Armory one place the Counting Room Vault key can turn up, so search the lockers before you leave. If it is there, the key takes you from the Deadtown school to the casino counting room in Cheongun Village; the Counting Room Vault key guide covers that vault.
