Full Metal Jacket is the 1st upgrade of Path 1 for the Sniper Monkey in Bloons Tower Defense 5 and BTD6. This upgrade allows the Sniper Monkey to pop 4 layers of the bloon that it hits as well as lead bloons. This tower is extremely useful for clearing out small groups of bloons but is not as good when trying to attack compact groups of bloons such as Round 76. It is inadvisable to use this along with towers with low popping power as the bloons popped will spawn a dense pack of weaker bloons, like yellows.
