RSO Range Facility Design and Physical Infrastructure

Question 1

What is the primary purpose of a range's earthen berm or backstop?

Accepted Answer

To stop projectiles and prevent rounds from leaving the range boundaries, protecting people and property beyond the range

Answer

To provide a mounting surface for paper targets

Answer

To reduce noise levels for neighboring properties

Answer

To serve as a visual boundary marker for the firing line

Question 2

A range RSO observes that the earthen berm behind the target line has developed a visible erosion channel or 'washout' cut through it by rainfall. The correct immediate response is to:

Accepted Answer

Temporarily close the affected range lanes and notify management immediately, as berm integrity is a critical safety issue

Answer

Monitor the channel and document it in the next scheduled quarterly inspection report

Answer

Place additional targets over the washout to discourage shooters from aiming at that area

Answer

Allow shooting to continue since the berm is still mostly intact

Question 3

On an outdoor range, 'baffles' or 'overhead baffles' are installed primarily to:

Accepted Answer

Prevent shooters from firing at angles that could send rounds outside the range's safe fan, by restricting the upward and lateral angle of fire

Answer

Reduce the effective range of firearms to protect neighboring properties

Answer

Block wind from affecting accuracy at longer distances

Answer

Provide shade for shooters on the firing line

Question 4

The 'danger fan' or 'cone of fire' on a shooting range refers to:

Accepted Answer

The angular area downrange within which all projectiles must remain to keep the range safe, determined by the range's layout and baffle design

Answer

The area immediately behind the shooter where spent casings are ejected

Answer

The safe zone for range officers to stand during live fire

Answer

The area around the muzzle where hot gases create a burn risk

Question 5

When establishing the firing line on an outdoor range, the distance between the firing line and the target line should be determined primarily by:

Accepted Answer

The backstop's height, construction, and ability to safely capture rounds fired from that distance at the expected calibers and trajectories

Answer

The personal preference of the range owner

Answer

The average accuracy of shooters expected to use the range

Answer

Federal minimum standards that apply uniformly to all ranges nationwide

Question 6

An RSO is reviewing plans to temporarily add a new target position that would require shooters to fire at a 15-degree angle toward the side berm rather than directly downrange. The RSO should:

Accepted Answer

Reject the change and require a formal safety review, as angled fire may direct rounds outside the designed danger fan or into adjacent lanes

Answer

Approve the change, as minor angular variation is standard practice

Answer

Approve the change only if the side berm is made of concrete

Answer

Allow it only for experienced shooters who have demonstrated accuracy
