From an AP obit by Susana Hayward headlined “Patrick Hamilton, ex-AP and Reuters photographer who covered Central American wars, dies at 74”:

Patrick Hamilton, a combat veteran of the Vietnam War who covered civil wars in Central America as a photojournalist for The Associated Press and later worked at Reuters covering the first Gulf War in Iraq, has died after a long struggle with cancer.

Hamilton’s experience in Vietnam served him well in Central America during the 1980s and then with Reuters, for which he covered Operation Desert Storm in 1990.
