monument respawn

[final pasture]

I was wondering how long it takes for loot crates to respawn at monuments like the airfield? let me explain, I made the blue card there and there were no boxes, is it good to wait for them to appear?

20-30 mins.
I do not suggest waiting inside the room, will take longer to respawn.

20-30 minutes if not waiting at the monument generally 45-60 minutes if your waiting at said monument

no
