dont use Small Yellow Cover they Clump Up Together, if U talk about USF Nade, Riflenade, Shock nade
Guard nade, UKF nade will also kill those in Small yellow Cover
Guard nade wipes squads in any cover, there is no argument there. Unless you start moving before the animation begins you lose models. The thing has been OP since the game came out and has somehow survived.
Allied nades are always better, for less cost. Look at the british nonsense. People had a tantrum over the incendiary grenade because they finally had to deal with an axis grenade that wasn't something purchased from a halloween store.
Look at bundled nade for example, 50 munitions for a good chuckle. Thing detonates like a mininuke from fallout and does damage equivalent to someone being hit by confetti.
