Due to the influence of international concepts such as “Gender Mainstreaming” and “Gender Equality,” the policy changing of National Armed Forces service and the reduction of recruited draftee, the performance of military womanpower has broken through previous limitations. NCOs (non-commissioned officers) play the roles as both conductors and followers, and they are the practical executors in the frontline. This research is to discuss whether or not female NCOs receive restrictions in the military troops which are mainly organized by male personnel and have more restrains than in civilian enterprises, what predicaments female NCOs should experience, and what advantages female NCOs might benefit than male military personnel just because of gender. This research takes in-depth interview of ten female NCOs in service for achieving purposefulness and convenience from February to April 2017. The interviewees are three Master Sergeants, three Sergeants, two Staff Sergeants, and two Corporals. The results found that female NCOs feel restrained most strongly by the following three: “gender being the factor of working dispatch,” “poor facilities and awkward management for livelihood,” and “self-contained and standardizing working environment.” The predicaments which female NCOs experience are the following six: “unreasonable leadership of senior cadres,” “having no confidence in sex harassment prevention system,” “discrimination for promotion,” “insufficiency of manpower,” “having obstacles in leadership,” and “unable to take care of family at the same time.” The advantages which female NCOs might benefit than male NCOs are “senior cadres are more gentle to female NCOs,” “having better chance to transfer to a higher post in certain jobs,” “being influential in some policy revising.” This research concludes that military troops do possess limitations for female NCOs; however, those limitations are abrogated gradually. Furthermore, both predicaments and advantages which female NCOs encounter come from the factor of human. To create amicable working environments for female NCOs, this research recommends that the Ministry of National Defense keeps on reformation, educates the cadre good leadership to build a sound sex harassment prevention system. Male military personnel should build proper notion of gender mainstreaming to create nice working environments, and female NCOs should set good examples by working hard and employ ones’ own distinguishing characteristics to bring diversifications in management and innovations to military troops.
