UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA

MICHAEL FISSLER, et al., Plaintiffs

v. Civil Action No. 18-3122 (CKK)

ISLAMIC REPUBLIC OF IRAN, Defendant.

AMENDED MEMORANDUM OPINION1

This case is one of many in this jurisdiction arising from terrorist attacks on coalition soldiers during the American invasion and occupation of Iraq. Plaintiffs are surviving U.S. servicemembers and heirs who seek to hold Iran responsible for the role it allegedly played in a number of these attacks. They have sued the Islamic Republic of Iran (“Iran”) under the terrorism exception to the Foreign Sovereign Immunities Act (“FSIA”), 28 U.S.C. § 1605A, asserting that Iran provided weapons to Shi’a paramilitary groups that they allegedly used to harm Plaintiffs. According to Plaintiffs, Iran equipped and trained these militias to execute attacks employing improvised explosive devices (“IEDs”), explosively formed penetrators (“EFPs”), and improvised rocket-assisted mortars (“IRAMs”). Before the Court is Plaintiffs’ [29] Motion for Default Judgment and [37] Supplemental Motion for Default Judgment on behalf of Plaintiff Jonathan S. Schmidt. As Defendant has failed to appear, default has been entered, and Plaintiffs now move

1 This Amended Memorandum Opinion amends the Court’s [40] September 26, 2022 Memorandum Opinion. The Conclusion section of this Amended Memorandum Opinion is amended to include the names of Plaintiffs Ki Moon (mother of Jae Sik Moon, deceased), Robert Reuter, and Bobby Wilson, Jr., whose claims were encompassed by Plaintiffs’ [29] Motion for Default Judgment, which this Court granted by means of its [39] Order accompanying the [40] Memorandum Opinion. This Amended Memorandum Opinion is also amended to correct some minor typographical errors.

for default judgment on liability only. Upon consideration of the briefing,2 the entire record, and the relevant legal authority, the Court shall GRANT Plaintiffs’ [29] Motion for Default Judgment and [37] Supplemental Motion for Default Judgment on behalf of Plaintiff Jonathan S. Schmidt.

I. BACKGROUND AND FACTUAL FINDINGS As explained in more detail in Karcher v. Iran,3 396 F. Supp. 3d 12 (D.D.C. 2019) (CKK), the United States designated Iran as a state sponsor of terrorism in 1984. Id. at 22. During the American occupation of Iraq, the Qods Force of the Islamic Revolutionary Guard Corps, a division of the Iranian military, funded, armed, and coordinated with several Shi’a militias in Iraq to counter American influence in the region. Id. at 24-26. Iran and Iranian-associated groups provided funding and training to Iraqi militias. Roberts v. Iran, --- F. Supp. 3d ---, 2022 WL 203540, at *4 (D.D.C. Jan. 24, 2022). The Qods Force developed and provided a particular weapon, the EFP, to these militias. Pennington v. Iran, Civ. A. No. 19-796, 2021 WL 2592910, at *4 (D.D.C. June 24, 2021) (JEB). The EFP is a particularly powerful IED that is capable of penetrating and destroying up-armored Humvees and other U.S. military vehicles. Roberts v. Iran, --- F. Supp. 3d ---, 2022 WL 203450, at *5. A sophisticated explosive, it consists of a “steel pipe” with explosives packed behind a “precision manufactured concave copper disk liner.” Id.

2 This Memorandum Opinion focuses on the following documents:

• The Complaint, ECF No. 1 (“Compl.”);

• Plaintiff’s Motion for Default Judgment, ECF No. 29 (“Mot.”);

• Plaintiff’s Supplemental Memorandum for Default Judgment on Behalf of Plaintiff Steven Julianna, ECF No. 33 (“Supp. Mem.”); and • Plaintiffs’ Supplemental Motion for Default Judgment on Behalf of Plaintiff Jonathan A.

Schmidt, ECF No. 37 (“Supp. Mot.”)

In an exercise of its discretion, the Court finds that holding oral argument in this action would not be of assistance in rendering a decision. See LCvR 7(f). 3 For ease of reference, the Court refers to Defendant, the Islamic Republic of Iran, by the more commonly used “Iran.”

As the Court explained in Karcher, and incorporating Karcher’s factual findings here, detonation requires a “two-step armed and triggering process.” 396 F. Supp. 3d at 26 (internal quotation marks removed). The operator uses either a “command wire” or “remote frequency” (i.e., a physical wire as opposed to a radio frequency) to arm the EFP. Id. Once armed, an infrared sensor affixed to the EFP triggers detonation upon “sensing” the heat signature of a passing vehicle. Id. In part because the design and manufacture of an EFP “requires substantial technical expertise,” the use of an EFP in an attack on U.S. servicemembers during the occupation “all but necessitates the inference that Iran was responsible” for the attack. Karcher, 396 F. Supp. 3d at 30 (emphasis omitted).

Ryan E. Thompson, the Plaintiffs’ first proposed expert, opines that EFPs were responsible for the harms inflicted upon Chase Cullen, Adam Fargo, Jae Sik Moon, Robert Reuter, Shane Smith, Bobby Wilson, Jr., Nicholas McCoy, Michael Fissler, Dylan Hibbert, Nicholas McCarty, Jason Harrison, Steven Juliana, and Jonathan Schmidt. ECF No. 29-1 at 4-19 (“First Thompson Report”); ECF No. 33-2 (“Second Thompson Report”); ECF No. 37-2 (“Third Thompson Report”). Mr. Thompson is a licensed engineer with a specialty in systems similar to those at issue in this case and a retired Army lieutenant colonel. First Thompson Report at 3. While in the Army, Thompson was in a company that patrolled a military supply route between the Iraq-Kuwait border and Baghdad in order to clear it of IEDs, including EFPs. Id. at 4. Additionally, in both Iraq and Afghanistan, Thompson investigated IED incidents to educate U.S. and coalition forces about such weapons in all their local varieties. Id. The Court thus qualifies Mr. Thompson as an expert on IEDs, including EFPs, used against U.S. and allied forces in the most recent wars in Iraq and Afghanistan. In light of Thompson’s expertise, and the analysis in Karcher connecting EFPs in

Iraq to Iran, 396 F. Supp. 3d at 30, the Court accepts Thompson’s conclusions regarding Iran’s responsibility for the EFP incidents at issue here.

The remaining attacks involved two other kinds of explosives, improvised rocket assisted munitions (“IRAMs”) and vehicle-borne improvised explosive devices (“VBIED,” also commonly known as “car bombs”). Plaintiffs’ second proposed expert, Phillip Smyth, explains the engineering of these devices and their links to Iranian-backed terrorist groups in great detail. See generally ECF No. 29-1 at 22, Expert Report of Phillip Smyth re: Plaintiffs Joseph James III, Shaun Cook, Frida Catherine Nicole, and Randall Burns (“Smyth Report”). Smyth has published several articles on Iranian proxy groups and their tactics since 2006. Id. As a resident fellow at the Washington Institute for Near East Policy and the University of Maryland, he also researches and publishes on Iranian-backed militants operating in Lebanon, Pakistan, and other countries. Id. at 22-23. He has also given guest lectures at American universities, been featured in syndicated news outlets, and has testified before Congressional committees on the subject of Iranian proxy groups. Id. at 23-25. The Court therefore qualifies Mr. Smyth as an expert in (1) the relationships between Iran and the militia groups it has backed and (2) the explosive devices used in attacks by these groups.
