OP, just in case it was not abundantly clear from the thread respondents, you do not have to go through the traditional RCIA route in order to receive the Sacrament of Confirmation(and your first Communion). I was near a church with a poor RCIA program and knew the priest in the next town over and was able to meet him one morning each week; this was essentially my RCIA instruction, and I suspect you could do something similar. However, what I think only one person responded to…
DO NOT RECEIVE COMMUNION just because you are going into a battle zone/ or other dangerous situation.
