Lost REQ Armory items

I have lost multiple in-game reqs during Halo 5 Warzone Firefight due to dropped matches due to my Internet connection. Is there any way to get these reqs back or replaced?

If a boost is applied and the criteria is not met for it to be redeemed (ie. finish / complete a match and the match is incomplete) the boost will be returned to you. It’s not immediate so it can take a few games, but the change was made a few months ago to make this happen

In addition to what stckrboy said, for single-use weapon REQs, if you leave a game while a REQ is in hand, that REQ will not be refunded. The moment you spawn with a selected REQ in a Warzone game, it is out of your REQ collection, and there is no way to put it back in. You’ll have to rely on random chance from REQ packs to restock that particular REQ.
