Most of the stuff I was in, you rarely saw who was shooting at you much less get a chance to aim no matter what your sights. Much of the time they shoot from good cover and from accross a barrier like a gully, rice paddy so they can't be quickly assaulted.
My approach to combat shooting is to place it in the tactical context. The purpose of shooting in combat is to win the fight, so your shooting program should be an integrated part of your tactics.
During the Viet Nam era, the Army emphasized “React to Ambush” or “React to Contact.” The idea was, if you were ambushed at close range (50 meters or less) you should charge the enemy. Otherwise, you should run away from the ambush. But if it were merely contact (and not an ambush) you should engage in a firefight.
To make this work, of course, you would need three additional men in the rifle squad – a tape man to measure the distance between you and the enemy, an interview man to question the enemy leader, “Were you set up for us, or were you just as flabbergasted as we were when the shooting started?” and of course a referee to call the close ones.
The point is, it doesn’t make sense to expect a man (let alone a unit) to instantly choose the correct response among three diametrically opposed options when under fire. So I established my own “React to Contact” drill.
1.
Take cover. This is automatic, anyway – why fight Mother Nature? And it’s logical – when the shooting starts all you know is that you’re in contact and you’re still alive. This means no high-speed metal particles have passed through the space you occupy. So the best thing for you to do is reduce the amount of space you occupy and get behind something, too.
2.
Locate the enemy. A lot of people who have never been in combat think this is easy. It isn’t. You need to train on the crack-thump method – when you hear the crack of the bullet, be alert to listen for the thump of the gasses escaping from the muzzle. That will tell you approximately where the enemy is. Combine that with looking for flashes, dust, and signs of movement to locate the bastards.
3.
Return fire. The taxpayer has provided you with all the ammunition you can carry. Use it – but use it correctly (more on this later.)
4.
Locate the men on your right and left. Small units disintegrate when first under fire. That’s natural, so it’s up to you to start putting your unit back together.
5.
Relay orders and information – restore the chain of communication and command.
Now let’s translate this drill into effective shooting. To understand how this works, go outside and lie down. Get low, as if your life depended on it (as it does in combat) and look in the direction of your imagined enemy. Visualize a horizontal line in space. Move this line down until you can confidently say, “There can’t be an enemy below that line.” Now imagine another horizontal line and move it up until you can confidently say “There can’t be an enemy above that line.”
Add left and right limits, and you now have a shallow box. The enemy is somewhere in that box, and if you can’t do anything else, you can methodically work that box, keeping all your shots into that narrow zone where the enemy has to be. If you spot evidence of an actual enemy location (dust, moving bushes, muzzle flashes, etc.) work that area carefully, shooting at and around the suspected location. Fill that space with bullets. But semiautomatic only – there is no good reason for full auto fire from hand-held weapons.
Now, you’re part of a unit. This is a collective enterprise, not an individual undertaking. So let’s make it a group effort; to do that we add the leaders’ duties. To accomplish this I had officers and NCOs load with solid tracer – other than machine gunners, only officers and NCOs had tracers.
The squad leader visualizes his squad sector using the same techniques as individual soldiers, then he marks the limits by firing two shots at the left limit, two at the right limit, and two at center of sector. This distinctive two-shot tracer fire, plus a standard left-right-center pattern alerts soldiers and allows men who don’t see the whole pattern to accurately estimate what their squad leader wants.
Now individual soldiers and team leaders divide up the squad sector. If I’m on a flank, I work that flank toward the middle. If I’m in the middle, I work the center of the target box toward both ends. I and my team leader want to see other men’s shots hitting in “my” part of the squad sector – so we know we’re delivering overlapping fire. NCOs want to see some shots hit short – a ricochet can kill, a high shot won’t do any good. Keep your fire low.
When a leader spots a suspected target, he begins to fire steadily at it – that stream of tracer tells everyone “Everybody shoot at this area.” Similarly, if a leader shoots full auto at a target it means “Machine guns concentrate on this area.” Leaders terminate fire concentrations by shooting the left-right-center pattern again.
Another combat problem is to get people to stop shooting. This is done by firing bursts of full auto tracer high above the target area. That means, “Hold your fire, dammit!”
These simple techniques, plus a lot of training and good squad supervision, will dramatically increase a unit’s kill rate in combat.
