By SLOBODAN LEKIC, JOHN VANDIVER AND KARIN ZEITVOGEL | STARS AND STRIPES Published: January 2, 2021 Twelve service members died on overseas deployments to designated combat zones in Africa, Kosovo and the Arabian peninsula region, including waterways, in 2020. One other soldier was killed in a terrorist attack in Kenya, which is not a designated combat zone. The most deadly of the incidents was a helicopter crash in the Sinai Peninsula in Egypt in November, in which five American troops died and one was injured. The Americans were part of an international peacekeeping force that monitors compliance with the 1979 Israeli-Egyptian peace accord. Henry J. Mayfield Jr.
