Metal Gear Solid: Peace Walker/Extra Ops 003 - Target Practice Score Attack

Mission Prep
It is suggested you be very comfortable with the gunplay and have a highly accurate, highly-upgraded weapon with a high magazine capacity. If you're going to attempt the S-Rank as soon as this mission becomes available after completing Metal Gear Solid: Peace Walker/Contact the Sandinista Comandante, bring the ★1 M16A1. Do not bring a sniper rifle, the rate of fire is too slow and the magazine capacity too minuscule. If you have it, do not bring the Sneaking Suit as it reduces precious ammo capacity.

Mother Base Shooting Range
You have 3 minutes to shoot as many targets as you can. The number of targets is unlimited. S-ranking this mission is dependent on accuracy rather than time; get too many shots in the white of the target and you effectively lose the S-rank. Roughly 23,000 points are what you need to get the S-Rank. Attempt a headshot every time, and a body shot on moving targets and distant targets. If you are less than the 23,000 points when you're running out of time, restart the mission. Try to memorize where targets appear. There is a cyclical sequence; the order doesn't change, but it gets faster as you reach the end of your allotted time.

Completion
This mission provides no progress toward the completion of R&D projects or Outer Ops. There are no rewards for completing this mission. The Heroism yield for any rank under S is 7 points; falling short of an S-Rank despite any effort is literally the same as just standing there until time runs out. The only reason to participate in this mission is to ultimately S-Rank every mission in the game. The Heroism yield for S-Ranking the mission is 22, which may be useful in the early game. Otherwise, move on until you have something with a laser sight and three other players.
