loadout - extra granades ?

Games Halo 5: Guardians
1

I haven’t unlocked a single load-out yet and i have been playing a lot, are they that rare or am i just unlucky ?

2

They are not all that common.

3

I have the extra grenade one and that’s it

4

I would of thought the others would be more helpful since you can just pick them up

5

They are different rarities.

Frags = Rare
Splinter = Rare
Plasma = Ultra Rare

I have bought a bunch of packs and only have the Splinter one.
