Using the Scorpion as a test vehicle to measure grenades power levels.
Frag Grenade: takes 8 to destroy if thrown under body and turret, takes 13 if thrown on top because of frags bouncy nature.
Plasma Grenade: takes 4 sticks to kill. 6 sticks on turret
Pulse Grenade : takes 4 if thrown under body and turret. Takes 5 if thrown on top…this is if both primary and secondary “Pulses” hit
Mantis and Wraith take the same amount as scorpion.
Warthog, monggoose, and ghost take 4 frags, 2 sticks and 2 pulse grenades.
Note: Ghost takes 2 plasmas with one shot from plasma pistol. And 2 pulse grenades with 6 shots from plasma pistol
Banshee takes 5 frags, 3 sticks, and 3 pulse grenades.
Note: Chances of getting kills with Frags and Pulses while Banshee is in flight is unlikely.
Might be old info, but it’s both useful for both driver and attacker.
Edit:Thise is done without the “explosive” perk to increase damage for grenades.
