How do I pickup weapons that my enemies dropped?

Just please tell me! XD

There is a button for default action.
Use it to open a door, enter a vehicle and pick up a weapon.
(I have it binded on T)

And don't forget to pick up ammo when you pick up weapon.

I believe it’s Z by default. And don’t forget to pick up ammo too, otherwise you will only have 1 mag.
