Simulated prayer?

I was watching this documentary, Full Battle Rattle, on a slow Sunday. It shows the simulated Iraq that the US Army maintains here in America, in the Mojave desert. Quite interesting to look at, as performance art and theater. I'm not gonna review the whole film. It's on Instant Watch on Netflix if anyone is interested, quite neat. The part that I found quite odd was after a simulated attack on the foward operating base. Medics were treating simulated casualties on actors and a Chaplain was praying over an injured man that turned out to be a mannequin. The prayer the Chaplain gave was not at all indicative of the "false" nature of it, asking for help and safety for this "man".
