In a military camp set in an ample, open field, a temporary medical checkup area is established to monitor the health of the soldiers. The setup includes various stations separated by tall opaque curtains that reach from just above the ground to a height of six feet, ensuring privacy while someone is standing or sitting. The curtain partitions create several corridors and enclosed areas for different medical procedures. The medical staff, consisting of doctors and nurses, wearing white coats, move freely between the stations.

Private Yamina is tasked with guiding her fellow soldiers through the checkup process. After briefing them on the procedure, she sees them to the first station, where height and weight are measured. As each soldier steps behind the curtain for privacy, Yamina cannot see their particular measurements, but she observes their general demeanor as they exit, trying to gauge their stress levels.

To the right of the weight station, there's a blood pressure check area. Private Emeka is currently seated there, a curtain partly obscuring him. Only the top half of his body is visible to those walking by. Nearby, Specialist Leilani is preparing to draw blood from Corporal Jaxon, who sits in an enclosed area. The curtains around this area reach all the way to the ground, ensuring no one can view this procedure. A clear path exists from each station to the exit, but due to the placement of the curtains, one must navigate a bit like a maze.

From her position at the entrance, Yamina hears Jaxon's faint laughter from behind the curtains and ponders how much of his interaction with Leilani is audible to Emeka, who is closer to that station. Concurrently, Emeka, while unable to see the blood drawing process, is trying to listen to see if he can discern any discomfort from Jaxon to mentally prepare himself for his turn.

Later, while escorting a group to the eye examination station, Yamina ponders whether the personnel at the nearby hearing test station might be able to glean any visual cues about reactions to the hearing tests since the two stations are in close proximity, separated only by a semi-transparent mesh curtain. This curtain is designed to allow light and sound through while offering minimal visual privacy. The question arises as to what those at the eye exam station can see of the hearing test through this mesh and vice versa.

Lastly, Yamina reflects on the privacy of the enclosed changing area, which has an opaque curtain that does not totally reach the floor with about a two-inch gap beneath. When a soldier bends down to tie their shoelaces after changing their clothes, Yamina wonders if their head and shoulders might be visible to people outside the changing area. What would an observer standing directly in front of the curtain or at a significant angle to it be able to see of the soldier tying their shoes inside?
The medical checkup area, with its curtain partitions and various stations, allows for privacy in most activities, but the spatial arrangement and material of the curtains influence what can be seen or heard. When Private Emeka is at the blood pressure check area, the top half of his body is visible due to the curtain height. This means that while Emeka cannot see any part of Corporal Jaxon that is obscured by the ground-reaching curtains at the blood drawing station, the sound of Jaxon's faint laughter is audible. While sound travels around barriers, Emeka's direct line of sight does not permit him to discern any visual information about the blood drawing procedure. However, being closer to this area, Emeka may pick up some clues about the interaction between Jaxon and Leilani based on their voices and laughter, without specific visuals.

At the eye examination station, the semi-transparent mesh curtain offers minimal visual privacy while allowing sound and light through. Staff and soldiers present at the eye examination station might observe blurry movements through the mesh when someone at the hearing test reacts to a sound. These vague silhouettes can give an impression of someone's movements or posture, but no clear details can be discerned. Conversely, those at the hearing test might also catch these visual hints from the eye exam but would not see any detailed activities.

Regarding the changing area with the opaque curtain that hangs a couple of inches off the ground, privacy is compromised when someone inside bends down. Their head and shoulders could potentially be visible from outside the curtain, especially to someone directly in front of it. However, the degree of visibility would depend on the soldier's proximity to the curtain. The closer they are, the more an observer might see. If a soldier is significantly far back from the curtain or at an angle, less of them would be visible. Someone standing at a sharp angle to the entrance has a reduced chance of seeing the bent over soldier due to the perspective; only a sliver of the interior would be visible to them, if at all, depending on their distance and the angle relative to the curtain.
