sniper stalking techniques

 Stalk training is the component of sniper school that hones a sniper's stealthy approach. Snipers have to learn to move slowly, patiently and methodically. If necessary, snipers will lie for days in the same position to observe an objective or avoid detection. Army Ranger Sniper describes the intricate process:
When you're stalking, you would be amazed when you're on the ground the things you walk over and don't look at. When you're trying to sneak up on somebody, even an anthill looks like a mountain. You have pick out your positions -- the next place you're going to crawl to. You ask yourself, "Is that going to cover me when I get there, and how am I going to get there?
To develop this ability, snipers have to pass perhaps one of the most challenging training games -- the stalk.
Stalk training takes place in open grassy ranges. Students start at one end of the range. One thousand meters down range, two instructors sit on top of a truck or tower with spotter scopes. Sniper students must stalk toward the instructors without being seen. To add to the challenge, the instructors have two soldiers in the field called walkers. The instructors use radios to communicate with the walkers and try to find the sniper.
Students must stalk from 1,000 meters out to within 150 meters of the instructors, all the while avoiding detection by the instructors and the walkers. Once in position, they take a shot (they are firing blanks). They must take this shot carefully because if their muzzle flashes or kicks up dirt, then they can be easily spotted. After the first shot, the snipers must stalk to a second firing position and take a second shot. To verify that the snipers were actually sighting the instructors, the snipers must read the card or count the number of fingers the instructors are holding up. Stalk training is a pass or fail game. If the sniper is spotted at any point, he fails the game. Too many fails, and the student washes out of the program.
Of course, training exercises are different from deployment. Army Ranger Sniper explains it this way:
"In the real world, it's a lot easier to get up to an objective than you would think. When we did stalks, [the instructors] would have us get up to within 150 meters of the objective. In the real world, you would never get that close to an objective. The real world is actually a lot easier."
Anywhere, any time, snipers are prepared to use their specialized skills to sneak into dangerous situations and disable an enemy force through a combination of close reconnaissance and deadly long-range fire.

Accuracy: According to MIL-R-71126(AR), the rifle shall achieve the accuracy results stated below when using M118 Special Ball and fired from a Government approved machine rest. The average mean radius shall be less than or equal to the following values:
  • 200 yards (182.9 m): 1.3 inches (0.621 MOA)
  • 200 metres (218.7 yd): 1.4 inches (0.611 MOA)
  • 300 yards (274.3 m): 1.9 inches (0.605 MOA)
The actual rifle requirements for accuracy were .35 MOA from a machine rest and according to Major John Mende (ret.) this accuracy had to be maintained to 10,000 rounds. He stated, "Interesting side note was there was a 10,000 round requirement for the barrel to maintain the original accuracy. In fact after some 10,000 round tests we discovered the accuracy improved. A few barrels were tested past 20,000 and accuracy never went below the original accuracy requirement."
Maximum effective range is given as 875 yards (800 meters), but record shots have been made with the M24 at over 1,000 meters (1,094 yd). Meanwhile, the standard optical sight has a maximum elevation adjustment of 1,000 meters (1,094 yd).
