Army letter describing the religious needs for Pesach.  While this is for Army commands, it can be used as a form letter for any branch.

What I recommend doing is to retype this letter so it applies to your own command and submit it to the command chaplain or an appropriate member of your chain of command, so it can be distributed to the units at your location.  Sending stuff like this out goes a long way to solve problems with Jewish troops asking for days off, or arranging for special needs (dietary, etc.).
