Health care systems operate differently in every country and are products of historical and political factors. We compared health care systems for career soldiers in various countries with those of the Israel Defense Forces. Questionnaires requesting data regarding military health care services provided in their countries were sent to military attaches serving in Israel. The countries for which data were gathered include Argentina, Brazil, Chile, China, England, France, Finland, Germany, Hungary, Israel, Poland, Romania, Spain, and the United States. In most countries, career soldiers receive better health care services than civilians, especially in countries with military rule or under military threat.
