What use is the water pistol?

I have unlocked the Water Pistol after completing the right side objective of the right main mission.

Now that I have it, it seem to have unlimited ammo, but just blind for 2 ~ 3 sec the Mother Base guard if I headshot them.

Out of holding up, is there any use to this weapon? Or is it a joke weapon like the Banana was in Peace Walker?


The waterpistol has some uses:

  • Can hold up enemy soldiers
  • Can be used to distract soldiers. Shoot on the ground/wall near a guard and they will investigate the sound.
  • Can extinguish fire. Useful to extinguish those barrel-fires
  • Can be used to clear mines (mines will explode when shot)
  • Can be used to blind/stun enemies for a short time. If you manage to shoot an enemy directly in the face, they will be stunned for a short period.
  • Can be used to disable electronics silently. Just shoot at electronics and they will be disabled. This works on Communications Equipment (Radar Dishes), radio transmitters, power supplies etc.
  • Can be useful against skulls. When shot, skulls will absorb the water, which stuns them briefly.

  • Can be used in the fight against the man on fire. It can stop him from doing some attacks. It's also possible to extinguish him, but that takes roughly 3-5 magazines.
