Field Notes is where Penn Tactical Solutions publishes operational insights, clinical updates, and perspective pieces from active practitioners across emergency medicine, law enforcement, fire, and tactical medicine.

This is not a marketing blog. Every piece published here is written by someone who has worked the scenario, managed the call, or trained for the situation. We publish what we learn so others can be better prepared.

Have something worth sharing? We accept contributor submissions from qualified practitioners. Selected contributors receive a $25 gift card or a Penn Tactical t-shirt of their choice.
