Our guest medic editor this quarter is Devin DeFeo, a former SOF medic. 2LT DeFeo enlisted in the Army in 2004 and served as an 18D with 1SFG(A) and USASOC. As a medic, he authored the concept for MARCHE2 for TCCC in the chemical, biological, radiological, and nuclear (CBRN) environment published in JSOM, which later formed the framework for the Joint Trauma System Clinical Practice Guidelines on CBRN medicine and the CBRN chapter in the Ranger Medical Handbook. He then participated in the Enlisted to Medical Degree Preparatory Program (EMDP2) at George Mason University, earning a master of science in biology. He is currently a third-year medical student at the Uniformed Services University of the Health Sciences (USUHS). 2LT DeFeo is considering a residency in emergency medicine. He will be reviewing Does Mental and Visual Skills Training Improve High-Value Target Identification and Marksmanship Among Elite Soldiers? by J. Jay Dawes, et al. (p. 22).
