The Weapon Drop is one of the Field Upgrades featured in Modern Warfare. It sends an airdrop to the location marked with a Smoke Grenade. The drop can give the player and teammates either an attachment to their current weapon or a customized weapon. The attachment is equipped regardless of the amount of attachments already on the player's weapon, and the customized gun replaces the gun currently held. It should be noted that with the weapon drop box, a player with 5 attachments on their weapon can add 3 more attachments, up to 8 total, using the box. However, the attachments are random, thus resulting in a mixed weapon, that can either be made better, or worse, or mediocre. Use with care.
