Agreed. I think that the ODST needs some form of special grenades like how in Halo 3 the Chief got the equipment to help him. Besides, wouldn't the ODST need it more than the Chief? They don't have as much health, they have a weak shield in the form of "stamina", don't have motion sensors, can't duel wield, aren't as acrobatic as the Spartans, and can't use equipment. I know there are things which benefit the ODST's like the VISR and grenade pouches, but special grenades won't have impenetrable shields, limited invincibility, or jumping pads. Can't hurt to have a smoke grenade or two right? :)
