Don. you would have to been one of the computer programmers to say you have shot one of those big ones (late VietNam era). In other words, the computer would fire the guns only when ALL the conditions were satisfied via the sensors and computations thereof. Yes, a football field square would be about 1.5 MOA at 26 miles. The naked eyeball cannot see more than 20 because the horizon would block all sight of the target. Remember, the shooting platform and weather throughout to the target is moving too. Of course, we can say the same for off-hand 1000 yard shooting too. ... felix
