Ha! we were spread out all over a country that didn't have a paved trunk highway until the year I left. For most of my time there a road grader leveled it out a few times a year. And it quickly became a series of potholes. And to even get to that road took a mile walk, a taxi ride, a ferry crossing, another taxi, another ferry crossing, and a taxi just to get to that road. Once the road was paved, they actually ran a bus on it. True, a chaplain could have been given a 4WD and made a circuit every two weeks or so, but we were lucky to even have a nurse. Even there another volunteer visiting me got malaria and I basically got to treat him myself. No way to get to the nurse, he was too sick to travel anyway, and so I treated him, pushing the anti-malarial faster than he could throw up. He could have died, because we had a nasty strain of malaria there.
The Catholic priest could get there in the dry season only. The guy who came was an old Irish missionary. There was no other kind of Christian presence in my neck of the woods but Catholic. Oh, once at a high school many miles away there was an announcement that there would be a mass the next morning. So I went. And it seemed a bit funny. The liturgy was a bit different, although in English. OK. It's Africa and things can be a bit different. The last mass I attended was in Jola and I got a running translation of that into Mandinka, so I wasn't too sure what was going on. And we had bats flying around in the church. They thought it was their building. Anyhow, turns out the one at the high school was Anglican. In the capital city there were some Methodists too, but it was a predominantly Muslim country, with some Animists and few Christians.
My son is in the Air Force and they DO have chaplain support, even when deployed overseas. It is a nice 'feature'.
What they really needed in that country was evangelization. What I should have been doing was serving in the same place doing more or less the same things, but with an explicitly Christian organization (something like VICS, Volunteers in Christian Service, a Canadian group was a group I ran into while in Sierra Leone) where I could openly spread my faith.
