It is not uncommon for military members and their families to meet regularly with people who share their faiths (despite occasional resistance to those meetings). Marines at Camp Pendleton have met for breakfast and atheists have gathered at Fort Hood.

In Hawaii recently, an article on the local chapel at Wheeler Army Airfield noted “Brown Bag Buddhists” have been meeting to learn about the Eastern religion.  The discussion group is not hosted by a Chaplain; instead, a local temple leader comes in to teach about his religion:

The “Brown Bags Buddhism” discussion group [is] an introduction to Buddhism facilitated by Rev. Kevin Kuniyuki, resident minister of the Wahiawa Hongwanji Mission.  

The US military generally does an admirable job of supporting the free exercise of its members, whatever their faith might be.
