The “Police Sniper Response to a Public Venue” course sponsored by the Texas Tactical Police Officer Association (TTPOA) provides the country’s best police precision rifle shooters—the cream of the SWAT sniper crop—the training and practice to achieve this level of ballistic competency.
Course Breakdown
The four-day course begins by ensuring that both the weapons and shooters are capable of delivering precision shots at any range. The students also visit local venues to learn what to look for and seek out when establishing an FFP (final firing position). The class quickly realizes the complexity and difficulty in operating in large arenas like Cowboys Stadium and why physical fitness for a sniper is essential. Classroom time is provided to teach the theory, equipment and practical applications of delivering accurate, high-angle fire.

Cute.
What’s going on? Is this standard training, or some sort of ‘pressure’ exercise or exam? A little bit of explanation might make this anecdotal clip(s) more illuminating.
If I had someone yelling “Shoot, shoot shoot! Quickly; shoot!” over my shoulder as in the first clip, he or she would get butt stroked so I could pay attention to what was going on.
