Castle can greatly slow down the enemies' progression by blocking doorways or windows with Armor Panels requiring a higher amount of destruction to go through. Since the Armor Panels are bulletproof, they are especially useful to cover up windows that are highly exposed to enemy fire.

These Armor Panels become extremely powerful when used in coordination with Mute's Signal Disruptors, as they will prevent the enemies from using any breach charges to break it, however, the bulletproof Armor Panels are no match for Sledge's Breaching Hammer and Ash's Remote Breach.

The Armor Panels are also easy to miss in areas where they blend in with similarly colored walls. As such, players should be more mindful of them and should communicate their locations to teammates.

The Armor Panels are regenerated when taken down, so feel free to take them down and allow passage for teammates/yourself.

Operators cannot break holes in Armor Panels easily, restricting them from looking through any holes made.

Despite being labeled as bulletproof, Glaz is able to penetrate through the Armored Panels, as well as completely destroy one in 12 shots.

Castle's Armor Panels can be destroyed manually if hit with a melee attack 12 times.

Armor Panels take increased time for defenders to pull off.

Armored Panels placed on doorways are not fully enclosed like an Armored Panel on a window as this means a well-thrown frag grenade can slip under the Armor Panel and explode on the other side.

However, both sides can peek shot underneath the crack of a doorway armored panel which can make placing a Breach Charge risky as the defender can easily kill the attacker by firing at their exposed feet.
