Normally in Warzone you initially spawn with the stock assault rifle and pistol, both level 1 REQs. As you continue to unlock new weapons from REQ packs, you will unlock additional weapons as various REQ levels, but some will be level 1 REQs. To switch to these after spawning, you need to visit a REQ station while still alive, since you don't have access to the load out menu when the game first starts.
Is there a way to set a starting or default loadout of level 1 REQs so I don't have to visit a REQ station before my first death?
