The Ghana Armed Forces has undergone a lot of changes over the years with advancement in modern CIS to knit together to ensure effective planning, decision-making and command and control (C2). The changes have affected personnel, equipment, internal and external operations and C2.  The drive for reforms in the GAF gave birth to the establishment of the Department of Defence Communication and Information Systems (DCIS) to achieve coherence and end-to-end management of CIS.  This study assesses the impact of Defence Communication and Information systems in the GAF in the next decade.  Determination of the roles of DCIS and whether DCIS is an integral part of GAF operations among others were analysed. The major challenges of DCIS in planning, decision-making and C2 was also determined.  Analysis was restricted to the information generated from the respondents.  A self- administered questionnaire and a key informant interview schedule were used to solicit information.  Regarding analysis on the role of the DCIS Department, it was obvious majority of the respondents knew the some of the roles of DCIS. The study also revealed that DCIS is an integral part of GAF strategic plan. However, majority of the respondents did not think the military intelligence outfit is in a position to provide efficient analytical and information collection due to lack of CIS integration in the Intelligent departments.  Generally it was evident respondents agreed that, the adoption of DCIS in the GAF has enhanced delivery of defence operations.  However,  it was deduced that the GAF lag behind in CIS adoption and the effective use of appropriate technologies due to challenges of finance, untrained staff and inadequate infrastructure among others. The empowerment of DCIS to explore the full spectrum of CIS can be realised in the next decade provided the current challenges are adequately addressed.
