So they called them and charged them not to speak or teach at all in the name of Jesus. But Peter and John answered them, "Whether it is right in the sight of God to listen to you rather than to God, you must judge, for we cannot but speak of what we have seen and heard."

Congress, considered and then failed to provide the protection for religious free speech which had been added to the Defense Appropriations Act. Currently, while not "against the rules" officially, it is within the ability of Chaplin's superior officers to order them to not pray "in Jesus name" anywhere outside of their Sunday Chapel services. and, as can be seen by the case cited above, there are those in authority who are more than willing to so order.
