What is the M320/GP30 LVG's use or purpose?

Solution 1:

There has been several videos on youtube (Lvlcap has a review on the M320 LVG). The LVG is similar to throwing a grenade but to a greater distance. The damage is comparable to a grenade. This is useful for maps like Metro to clear out the side stairs without getting too close (at least for me). Lvlcap has a good review on it. Also, if you have the FRAG squad perk, I think you get 7 LVG nades

Solution 2:

I wanted numbers, so I stopped being lazy and went to find out myself.

Standing on a hand thrown grenade does 112 damage.

Prone on a grenade does the same (112)

Standing on an LVG does 107 Damage

Prone on an LVG does 112

While this is still only an assumption, it was the only logical conclusion I could come up with, as to the difference in prone versus standing LVG damage.

The LVG projectile is also a different model, looking like an M320 round.

In summary: The LVG does the same damage over a smaller area.

Solution 3:

I would think the LVG grenade would be useful for hallways or tunnels where you know bad guys are but can't directly through a grenade at. It will bounce off walls and such before blowing up.
