Normally people clear rooms that they know are occupied with a Flash or Stun Grenade, or if they are out of those by simply running in and hoping for the best. The later isn’t exactly ideal so instead let me explain a quick way to misdirect your enemies attention so you won’t get shot when entering a building.

On their face the two types of special grenades in Call of Duty 4 may appear to be the same, but they are actually quite different. Both grenades are effective for around 6 seconds at close range after going off, but their similarities end there. Lets jump right into the comparison and review of special grenades in Call of Duty 4, remember this is general knowledge and might not be true for every single weapon and Call of Duty 4 playstyle.

Flash Grenades – Have a one second fuse that will go off even if the grenade is in midair. This is a disadvantage for long tossing the grenade because it is totally ineffective if it explodes in mid air. The flash grenade has a longer range than the stun grenade, 200-800. It will only damage the enemy if it explodes right next to the target.
When it does explode the flash grenade emits a high piercing noise completely blinds the target for up to of 6 seconds depending on how close the the enemy was to the blast. Screenshot of flash grenades effects at right. Read more
