Notes:
[1] Though the definition of moral injury is not settled, this definition is taken from Jonathan Shay, “Casualties,” Daedalus 140.3 (2011): 183. For an appreciation of the multidisciplinary discussion, see Joseph Wiinikka-Lydon, “Mapping Moral Injury: Comparing Discourses of Moral Harm,” Journal of Medicine and Philosophy 44.2 (2019): 180-181.

Harold G. Koenig and Faten Al Zaben, “Moral Injury: An Increasingly Recognized and Widespread Syndrome,” Journal of Religious Health 60.5 (2021): 2989–3011, and Haleigh A. Barnes, Robin A. Hurley, and Katherine H. Taber, “Moral Injury and PTSD: Often Co-Occurring but Mechanistically Different,” The Journal of Neuropsychiatry and Clinical Neurosciences 31.2 (April 2019), 99: “Moral injury is not classified as a mental disorder. It is a dimensional problem that can have profound effects on critical domains of emotional, psychological, behavioral, social, and spiritual functioning.”
[3] Wayne Phelps, On Killing Remotely: The Psychology of Killing with Drones (New York, NY: Little Brown and Company, 2021). Despite the tagline in the title, it should be noted that Phelps seems to detest the term “drone,” and so I will follow suit referring to remotely piloted aircraft.

Bryan, Martha Schmitz, Claudia Villierme, Jessica Walsh, and Shira Maguen, “Moral Injury: An Integrative Review,” Journal of Traumatic Stress 32 (June 2019), 357. In their words: “It is unclear how (and whether) moral injury fits into current models for classifying psychiatric disorders […] research needs to establish thresholds of moral distress that evoke psychiatric and functional problems that merit clinical intervention, especially given the absence of criteria on which to base diagnosis or seek reimbursement for services administered.”

Nimni is critical of rightwing attempts to water down the term violence by incorporating property damage and theft, but also of leftwing attempts to water down the term by incorporating speech acts.

[11] “As would be expected, when you arrive on the scene in this situation, the friendly forces being shot at by the enemy express a wide array of emotions over the radio such as fear, anger, frustration, and impatience that can be felt and understood on the other end of the radio regardless of which crew position you occupy. Often troops’ lives depend on the integration and assistance of the RPA called to help them fight through the dangerous situation they are in. And you can hear the stress in their voice.” Phelps, On Killing Remotely, 73. Cf. 44.

They recommend that “crews must know as much as possible about their targets” and “they need the time, space, and boundaries to perform the moral homework to keep pace with their tactical actions;” they end their analysis with the encouragement that “tactics and approaches in keeping with the Just War tradition are, in fact, more effective on the remote battlefield.”
