Tactical Preschool
The following posts have been pretty popular at my blog. They tend to focus on LE tactics but I thought that the audience here may appreciate them. Any feedback or suggestions for new posts are appreciated.

I don't have a team to clear stairs. Thankfully I don't have to clear them being a civilian. In only the rarest of the rare occasion am I even in a building with them. If that rare occasion ever hits it would be even more rare for me to have to use them to escape, evade, or engage. Like hallways stairs are simply a bad place to be if shooting starts. Even with numbers its still bad.

I don't do sort of stuff anymore but I would think, instead of putting yourself/team members at risk, a couple of flash-bang grenades or tear gas cannisters would be the way to go.

Sharing good information is a very good thing. Sharing information that isn't any good, regardless of the intent, is a bad thing.
Your information includes the single lead rule used by the military. It is supposed to provide an easy means of compensation to account for the target traveling laterally to the shooter. The value is that the farther away the target is, the greater the compensation afforded by the rule. There are a couple significant problems with this. First, your presentation of the rule mentions nothing about it being a rifle-based rule. This rule does not work very well at all for handgun velocities except at close ranges. Second, the amount of compensation afforded by the rule very well may not be enough. Basically, the "rule" isn't as widely applicable as claimed. Since this is a miliary rule, let's use the M855 ammo from the M4 carbine. The M855 has a muzzle velocity of roughly 2800 fps and a BC of .304. Quote:
Using a ballistic calculator, it will take roughly .18 seconds for the bullet to travel from the muzzle to the target at 150 yards. At 7 mph, the target is traveling 10.27 fps. So in .18 seconds, the target will have traveled 1.85 feet (~22"). Putting your front sight just to the side of midline in the direction of travel gives you a 8" lead on the target's centerline. Since the target is traveling laterally to the shooter, the shooter sees the target's side. For ease of calculation, let's say the target profile is 12" wide. Since the target has moved 22", even with the 8" lead afforded by the single lead rule, the shot will pass behind the target. In short, the 22" of travel, minus the 8" lead lead of the centerline of the target leaves the trailing 6" of target left to be hit. So we subtract that 6" from the distance traveled by the target and that leaves us with 8" of travel not compensated for by the single lead rule. The round will miss the target, passing 8" behind it. Walking half the speed, 3.5 mph, the target will have moved 11" in the time it takes the bullet to travel the 150 yards. Subtracting the 8" lead leaves 3" of travel by the target and the trailing 6" left to be hit and so the round will impact 3" behind (from direction of travel) the centerline.

I bookmarked the blog, there is some interesting info there.
As Double Naught Spy points out, the single lead rule breaks down under long ranges and high or low angles. The blog and Double Naught's reply led me to look up the US Army Fm 3-22.9 Rifle Marksmanship manual. There is a lot more to this rule of thumb, and the manual breaks it down pretty well. The blog serves the purpose, though, to pique the interest to do more research. I don't think anyone should read a single blog, or article and think he has all the info he needs. Thanks, guys, good posts. |

Yeah.
There is a lot more to the blog than moving target shooting. Tactics, leadership, spiritual reflection. The articles that are directed or could be adapted to the individual (rather than team tactics) are most interesting to me. I definitely like the tone and content of the blog. |

Funny how the blog doesn't include the information from global security. If the global security web site has the proper information, then why not just link to it? I noticed that the blog doesn't include anything about the 60% failure rate noted in the supplemental information. The worst case scenarios of people running at a 90 degree angle happens quite a bit in urban environment as people cross the street from structure to structure.

I did add the link after you posted your first comment.
"Flat out would not work"? I didn't make this up myself. It's a technique taught by the Army. If you want "instruction" go find an instructor. This technique has worked just fine for me on the the moving target ranges I ever shot on while in the service. I wrote: Quote:

I don't believe I oversold this technique. Any reason this particular post is such an issue or is there some other problem?

If you are interested in the Armys research and decision to implement the single-lead rule; an abstract on their findings can be found here:

It's a rule of thumb. A starting point for boots who probably didn't grow up snap-shooting birds or taking pot shots at a running rabbit with a 22. It introduces an interesting method of using your sights to hit a moving target - and everyone who has ever shot a moving target knows a lot of probability is always involved.
Tgace made some additions to the entry which added color to the article. But, the blog site is about so much more, this is a minuscule part of the whole thing. If you are interested in tactics...or the classics; Bushido...or Kipling; fitness...or the "art" of being a man, this blog is cool. |
