It's not hard to find references to such studies. See eg "Scholars and polling organizations have also noted a consistent gender divide in public opinion on military action, beginning with World War II through the most recent U.S. wars in Afghanistan and Iraq, with men expressing higher levels of support for military action than women (Bendyna et al.,1996; Berinsky, 2009; Burris, 2008; Fite et al., 1990; Moore, 2002; Nincic and Nincic, 2002; Rohall et al., 2006; Shapiro and Mahajan, 1986; Smith, 1984; Wilcox et al., 1993)" (from https://www.academia.edu/1802567/Race_Gender_and_Attitudes_Toward_War_in_Chicago_An_Intersectional_Analysis https://www.academia.edu/1802567/Race_Gender_and_Attitudes_T... )
