Nobody can achieve great things alone. That is the reason I would like to show my gratitude to a number of people who directly or indirectly helped me in completing the present study. This study would not have been possible without the permission and support of Delta Company 6-101 GSAB Ft Campbell, Kentucky. I am especially thankful to CPT Düster for giving me an opportunity to do my research in the company. I must also thanks all non-commissioned officers, junior soldiers, and civilians who participated in the study for their precious time and relevant information without which the project would have been incomplete. I would also like to thank the Loua family and the Zouande family for their prayers and blessings. Finally I would like to thank
