Not true. The Israeli army removed women from front-line infantry positions because their research found that women were less physically-suited for the rigors of infantry life than men were.
The military study found that men could handle marches of 55 miles in length, while women had difficulty with distances over 32 miles. The difference was attributed to a 10% higher level of hemoglobin in men, which allows them to feed more oxygen to their muscles and aids in their ability to undertake extended physical activity.
The study also found that the average man could carry 55% of his body weight, while the average woman could only carry 40% of her body weight. This percentile difference combined with the fact that the average military-age woman weighs 33 pounds less than the average military-age man results in a 44-pound load difference when carrying equipment and supplies.
When the studies were concluded, the Isreali military made the decision to remove women from front-line infantry duties. Women were also barred from serving in tank crews, where each member of the crew must be capable of carrying out the loader's duties if needed. They may also be barred from serving in artillery crews or engineering units that deal with heavy equipment.
Women continue to serve in numerous other roles in the Isreali military such as pilots, navigators, naval officers, radar operators, intelligence officers, and light infantry units along peacetime borders.
