The Army said Wednesday that it would continue to open its elite Ranger School to all soldiers regardless of gender, after two women made history last month by becoming the first to pass the grueling leadership course. “We must ensure that this training opportunity is available to all soldiers who are qualified and capable,” Army Secretary John McHugh said in a statement. Army Rangers are rapidly deployable troops who often go after Special Operations targets. The 62-day course includes training in woodlands, mountainous terrain and Florida swampland for its students. The United States military began two years ago to open thousands of front-line combat jobs to women.
