From battlefield.wikia.com:
Battlefield 3: Close Quarters Players who have access to the Close Quarters expansion pack can use this ammunition with their M320/GP30 launchers. Instead of detonating on impact (40mm Frag), the projectile uses a 3-second timed fuse. The blast and damage are comparable to a hand grenade, and kills are awarded as grenade launcher kills despite firing a grenade. The LVG inflicts little or no striking damage.
My question is:
What is the difference between this projectile and a standard, thrown grenade and the standard HE?
More specifically, does it:
- Have greater range?
- Have greater damage?
(I.e: What is the point, beyond 'more grenades'!)
