I work for an agency that has a direct relationship with the armed forces as an 1811 and MOS/rank do not matter to them. All they care is to see that honorable discharge.
You are probably going to need mnore than just military as your background to get hired in federal law enforcement. My agency has a VERY STRONG history of hiring people who have local/state/other federal law enforcement experience. They have hired 20 in the past nine months and guess how many were not prior LEO's? None!
