Q1. What does OIC stand for?
ANSWER Officer in Charge — the individual responsible for the overall
conduct, safety, and control of a range or training event.
Q2. What does RSO stand for?
ANSWER Range Safety Officer — the individual designated to observe
and enforce safety rules on a live-fire range.
Q3. What is the primary duty of an RSO?
ANSWER To prevent accidents, injuries, and deaths by enforcing
range safety rules and monitoring all shooters and range activities.
Q4. What is the primary duty of an OIC?
ANSWER To plan, organize, supervise, and take overall responsibility
for all activities on the range including safety, logistics, and
administration.
Q5. Can one person serve as both OIC and RSO simultaneously?

separate. However, on small, controlled ranges with few shooters, one
qualified individual may perform both roles.
Q6. What are the three fundamental rules of firearm safety?
ANSWER (1) Always treat every weapon as if it is loaded. (2) Never
point a weapon at anything you don't intend to shoot. (3) Keep your
OIC / RSO Certification Study Guide | Page 1
, finger off the trigger until your sights are on target and you have made
the decision to fire.
Q7. What is a fourth commonly cited firearm safety rule?
ANSWER Know your target and what is beyond it — always identify
the target and be aware of the backstop and downrange environment.
Q8. Define 'muzzle discipline.'
ANSWER The practice of always controlling the direction a firearm's
muzzle points, ensuring it is never directed at anything the shooter does
not intend to shoot.
Q9. What is trigger discipline?
ANSWER Keeping the finger straight along the frame or receiver and
outside the trigger guard until the shooter has made a conscious
decision to fire at a confirmed target.
Q10. What does it mean for a firearm to be 'clear'?
ANSWER The firearm has been inspected and verified to have no
ammunition in the chamber, magazine well, or cylinder — it is safe to
handle without risk of discharge.
Q11. What is a 'safe direction' on a range?
ANSWER A direction in which an accidental discharge would cause
minimal harm — typically downrange toward the backstop or berm.
Q12. Define 'negligent discharge' (ND).
ANSWER An unintentional discharge of a firearm caused by a failure
to follow safety rules, such as having the finger on the trigger when not
firing.
Q13. Define 'accidental discharge' (AD).
ANSWER A firearm discharge caused by mechanical failure or an
external factor beyond the shooter's direct control, not by operator error.
Q14. What is the 'cold range' concept?

actions open except when directed by the RSO to load and fire.

shooting, take finger off the trigger, and await further instructions.

line.
Q22. What does 'RANGE IS HOT' mean?
ANSWER The range is active; firing may occur. No one goes
downrange. All firearms should be handled with full safety protocols.
Q23. What is a 'firing line'?
ANSWER A designated line or position from which all shooting takes
place, marked physically or by the RSO's designation.
Q24. What is a 'line of fire'?
ANSWER The path a projectile travels from the muzzle to the target
and beyond (the downrange area).
