All you need is a Field Kit, Containing Crucifix, candles, small chalice, etc .... Note in the picture , the use of a standard GI issue blanket to cover the hood of the Jeep.Everything fits into a box the size of a shoebox. As far as as wafers for the Host, Normal bread can be used in a pinch.

It's a little bigger (taller, anyway) than a shoebox, but not by much.
{I used to be a Chaplain's Assistant, so I got to work with the field-kit.}

The couple of times I went to mass in the bush (Vietnam) I had a few words with the Chaplin, being a old alter boy I was interested in his “Portable Church” as he put it
