Hiding objects on the map

[IGWedge]

Hi guys really basic stuff here...

I want to lay down some Ammo crates in my mission but i want them to not be visible on the map.
I tried searching but couldnt find anything. This is not something ive tried to do before now so im a bit stuck.

Also is it possible to have certain objects ie.. ammo crates or vehicles hidden from certain sides

Many thanks

Seems you are playing in Cadet mode, change difficulty level to Veteran.
