What are the 3 types of ballistics |
Internal External Terminal |
|
|
What are the two forces? |
Gravity- causes the bullet to fall Air resistance- causes the bullet to slow down Causes bullet to fly erratically and tumble |
|
|
How do shooters counter forces on the bullet? |
Increase angle of departure (elevate muzzle) Impart spin and high velocity |
|
|
What is line of sight? |
What the shooter sees behind the sights. Line from sights to the target |
|
|
Is all shooting the same? |
Yes |
|
|
Will the bullet always go where the barrel is pointed? |
Yes |
|
|
What are the 2 firing tasks? |
Properly point the rifle at the target (sight alignment)
Fire the rifle without moving it (trigger control) |
|
|
What is sight alignment? |
Centering the front and rear sights with the shooters eye |
|
|
What is sight picture? |
Addition of a target to properly aligned sights |
|
|
What is follow through? |
Continuing to apply the two basic fundamentals of marksmanship until recoil has ceased |
|
|
What are the four elements to a steady position? |
Support Muscular relaxation Natural point of aim Durability |
|
|
What are the 5 points of a solid position? |
Non firing hand Rifle butt Firing hand Stock weld Elbows |
|
|
What is the purpose of a firing position? |
Support the 2 basic fundamentals of marksmanship |
|
|
What is the MOA for the front sight of an m4 and m16a4? |
M4 1 click equals 1 3/4 MOA M16A4 - 1 click equals 1.5 MOA |
|
|
What is the MOA for a rear sight on an m4 and m16a4 |
M16a4- 1 click =1/2 MOA M4 - 1 click = 3/4 MOA |
|
|
These sights all have a 1/2 MOA |
M68 EOTECH ACOG- external knob ELCAN |
|
|
What optic has a 1/3 MOA |
ACOG - internal knob |
|
|
What is a parallax? |
Apparent movement or displacement of object when viewed from a different perspective |
|
|
What Is zeroing? |
Adjusting the sights so that the bullets impact where the shooter is aiming |
|
|
What distance do we zero? |
25m |
|
|
What is minute of angle? |
1 minute of angle is 1/60 of degree |
|
|
How do you calculate MOA given the inches and range? |
Inches ÷ range = moa |
|
|
How do you determine the inches given the MOA and range? |
MOA × range in hundredths 1(00) = inches |
|
|
Given the MOA and Inches how do you determine the range? |
MOA x inches = range |
|
|
What has the greatest variable effect on ballistic trajectories? |
Wind |
|
|
What are the elements of wind effects? |
Time the projectile is exposed to the wind (distance to target) Direction wind is blowing Velocity of the wind. |
|
|
What are the ways to read wind? |
Kestral or nanometer Study previous shots Watch trajectory through scope |
|
|
What is the formula for Wind MOA |
Range × velocity ÷ 7 =MOA OF drift |
|
|
What is the formula for half value wind MOA? |
Range x velocity ÷ 7 = MOA of drift Divide the MOA of drift by 2 |
|
|
What happens when the bullet leaves the bore of the rifle? |
It immediately begins to fall to the earth. |
|
|
T or F: battle sight zero and bullet drop compensating are 2 methods the army developed for engaging targets |
True |
|
|
What has the greatest effect on ballistic trajectories? |
Wind |
|
|
When reading wind, where do you focus on conditions? |
Halfway to 2/3 to the target |
|
|
Sight alignment + trigger control = |
Integrated act of firing |
