Ghana in Search of Regional Integration Agenda 34 post patrols, major events and international conferences fall in the ambit of the Operations schedule. 47 The GPS collaborates and coordinates with the Ministry of Foreign Affairs particularly as regards lectures at cadet training and workshops, and with CEPS and GIS(on issues of revenue/customs evasion, immigration irregularities and other cross-border criminal activities. In addition, the GPS collaborates with the Revenue Agencies Governing Board(RAGB) particularly its Revenue Protection Unit(RPU), a para-military body trained by CEPS, whose coordinator must have a security background, and monitors issues in relation to revenue evasion and whose activities influence the ECOWAS protocols. 48 To facilitate free movement of goods and persons, a recent directive from the GPS headquarters directed the suspension of all day barrier duties and the restriction of night barrier duties to only approved ECOWAS/NEPAD check points. 49 These approved ECOWAS/NEPAD check points are only nine across the Northern(Accra­Paga), Western(Accra-Elubo) and Eastern(Accra-Aflao) corridors. 50 By the directive, temporary night snap checks may be conducted between 6.00 pm and 6. 00am only at locations approved by regional commanders. The Ghana Armed Forces Regional integration always has a defence component since there cannot be economic development without peace. Thus, even though GIS and CEPS serve as the first point of call and frontline organisations in dealing with people at the borders, the Ghana Armed Forces(GAF) has been the lead security agency in dealing with the protection of Ghana's sovereignty and warding off external threats. The Ghana Navy, for example, is charged among other things with anti-smuggling operations at sea, prevention of landing of saboteurs, infiltrators and people engaged in anti-national activities and the security and safeguard of Ghana's shores; while the Ghana Air Force protects the territorial air space of Ghana and undertakes air reconnaissance operations. On its part, the Ghana Army has been assisting in halting smuggling, particularly in cocoa, across Ghana's borders and also mounting surveillance operations at the western and eastern entry points of the country. 47 Interview with outgoing Second in Command, Operations, Police Headquarters, 12 September 2008 48 Ibid. 49 Police Wireless Message, AC.131/379/01/A/TJ Suspension of Barrier Duties, 2 March 2008 50 For instance, there is only one such check point between Accra and Kumasi(at Doboro near Nsawam) and only two between Accra and Elubo(Korkrobite and Half Assini).
