Primary Grenades x2 is a Tier 1 perk in Call of Duty: World at War that gives the player two frag grenades, sticky grenades, or Molotov Cocktails. This is useful if the player relies on grenades for kills. It is unlocked at level 44. (Not to be confused with Frag x3 from Call of Duty 4: Modern Warfare, which gives you three frags, instead of two.)
