By God's decree, only able-bodied men were counted as able to fight. Although women might have fought in desperate circumstances against invaders, they were neither recruited nor accepted into Israel's army. The fact of men's superior physical strength and military mind has been universally recognized throughout history. Only the most delusional believe women can be as effective as men on the front line. Technology can compensate for much of the difference, but the natural disparity between male and female is by design.
