Reynolds was granted special leave to take the position with EUCAP Nestor based in the Kenyan capital Nairobi from on 19 July – the first time that the Irish Coast Guard has been involved in an overseas mission.
The role involves assisting local authorities with setting up their own coastguard service in a region that's been beleaguered by maritime piracy in recent years.
Ireland's coastguard chief is responsible for all operations and field offices of the EUCAP Nestor mission between Mogadishu, Puntland and Somaliland, as well as a training base in Djibouti.
Reynolds will return to his Irish Coast Guard post after his secondment, which the Department of Transport says will last around two years "subject to how the mission evolves".
Speaking of his appointment, Reynolds said: "I believe this is a recognition, on an international level, that we in the IrCG, both volunteer and professional, do a good job and that we have gained the respect and trust of all the communities we serve and all the partners we work with.”
