If you are convinced that Buddhism in some form is the path for you and are determined to follow that path in some form then there is no reason to delay taking refuge.
The refuge ceremony may or may not be problematic for you to attend/arrange. However you can take refuge daily by chanting:
Buddham Saranam Gacchami.
Dhammam Saranam Gacchami.
Sangham Saranam Gacchami
or in English
I go for refuge to the Buddha.
I go for refuge to the Dharma.
I go for refuge to the Sangha.
This refuge prayer is essentially totally ecumenical and is done in some form close to this in almost every Buddhist tradition.
The great Indian pandit (great teacher) who taught Buddhism in India and Tibet, Atisha, taught the refuge prayer practice widely. It is probably from him that Tibetans began the practice of reciting the refuge prayer (and other practices later) 100,000 times. It would be good, if you are determined to follow the Buddha's teachings, to recite the refuge prayer 3 times in the morning and three times in the evening (Indian Buddhist often did their practices 3 or more times in the morning and evening).
You can them take the formal refuge ceremony later according to the tradition that you decide to practice in. If I read your post correctly you are in the military. I used to be in the military and know that there are now Buddhist chaplains. So you could email them for advice on setting up the refuge ceremony if you wished. Here
is a link to the Buddhist Military sangha, a resource for Buddhists in the military.
