Armor Plates can be found in the open, in crates, or purchased from the store.
Armor Plates are everywhere in Call of Duty: Warzone, buildings, crates, and even the store for $ 1500 (which sells a five-pack of Armor Plates, nothing less). The armor in Warzone isn't cosmic - it doesn't come in tiers like most other battle royales. Hell, it's not even split between chest and head: armor is armor in Warzone.
You will always start a match with two plates installed, as indicated by the two blue bars above your health. You can have a total of three installed at a time, and replacing just one requires you to have an armor plate in your inventory. These caps are at five, but since there is no real inventory in Call of Duty: Warzone, you don't need to worry about them taking up space.
The Armor Break has a distinct burst sound, so if you lose track of your armor through the UI, you'll know it's time to replace your armor plates when you hear the crackle. When your armor is completely broken you start to damage your health, and the TTK in Warzone is the same as in normal multiplayer, so you'll have to install new armor plates right away if you don't want to. die. Once you need to replenish your armor, press the "4" key on your keyboard or hold down the Y / Triangle button on your controller. You can insert more than one at a time if you hold down the buttons, which is faster than equipping them individually.
That's all there is to arm in Call of Duty: Warzone. No helmets, no levels: only three bars that you fill with a single form of armor plate. Keep in mind that health will regenerate, so focus on grabbing those armor plates if you want to maintain an advantage.
