"hound"?
Your language betrays you. Chaplains should invite military personnel to their services; this is proselytizing and there's nothing wrong with it. As a Christian, the Chaplain might then have a sermon at that service in which they quote Jesus, "None come to the Father but through me." Then they should answer any questions that come up. Spritual pressure? You bet.
Nice scenario, but that's not what's at issue.
