This study was designed to evaluate the relationship between communication skills of managers and commanders (verbal, listening, and effective) on the organizational commitment of Army personnel. The k² test was used to analyze the relationship between the independent and dependent variables. Then, magnitude of the correlation coefficient of that relationship was evaluated. In the workplace, managers (managers, deputies ,commanders and all the decision-makers are included) with poor communication skills  are source of many organizational problems and their inability to communicate effectively reduces efficiency and increases dissatisfaction and causes lack of organizational commitment in the organization. Hence, some experts consider communication key to success in management. Thus, effective management and a balance in communicating with employees are the most important issue that should be considered for growth and excellence in any organization. The results show that there is strong  relationship between managers' communication skills (including verbal skills, and listening) and organizational commitment in Army. Communication skills are Prioritized as: 1.  Effective  2. Verbal  3. Listening.
