Upcoming Grenadier armor mod

Does anyone know what this mod will do?

Maybe grenade regeneration.

Im thinking extra grenade damage

In Halo 4 it allowed you to carry 1 more grenade capacity, so 3 nades instead of 2. However, those are already in the game so it has to be something close to the Halo 4 Packages/Support

I’m assuming it’s “Explosives” as it has the same holder image.

All “Explosives” did was increased the blast radius and reduced incoming grenade damage.

So we’re most likely getting the first half, the second half, or the entire ability itself from Halo 4. As we’ve already got a few more of the Halo 4 tactical/support packages in Halo 5.
