Resourceful Infection Medal

So i am attempting to get all of the medals possible in Halo 5. The resourceful medal in the infection playlist has been a nuisance for me. Does anybody know of an easy way to get the medal? Do i have to use melee attacks when out of ammo? Or can I utilize grenades? Do grenades count as ammo?

All information is appreciated.

Thanks

I have gotten quite a few of these when all my ammo is gone in one weapon and I get a kill with the last shot I have with my shotgun.

I got a resourcefull when my both guns were out of ammo by hitting a zombie

Well it looks like through some testing i have eliminated the grenade possibility. I got a cluster luck with no ammo and still no resourceful medal. Looks like i will have to find a way to melee a zombie, sword makes it tricky haha.

I was finally able to obtain the medal. Thanks to all.
