You might want to check out My Own Meals. They are a reputable company with shelf-stable meals that are approved by the military.
I don’t know the chain of command that you need to use, but I’m sure that someone will be able to help you.
There are also other Jewish items that you should be able to get via your chaplain or supply officer. Such as Kosher for Passover Seder Kits, Haggadahs, Kiddush Cups, Shabbat Candlesticks and Candles, Mezzozot and Klaf (Parchment), Tallits and Yarmulkes, Siddurim, Torah, Psalms, Kosher Wine, Menorahs and Candles, Bibles and more.
