The Military are by law not allowed to get involved in law enforcement unless some kind of National Emergency is declared.
Are you willing to live under Martial Law?
How would using military resources to intercept non-U.S. citizens from entering the country equate to putting U.S. citizens under martial law? This is the same line of logic that says that the detainees in Guantanamo should be given the same rights as U.S. citizens.
The Constitution, and its protections, only apply to U.S. citizens. People illegally attempting to enter the country are non citizens, and are trespassing.
OK I'll type slower so you can keep up.
Possee Comitatus basically states that Military Personel cannot be used in Law Enforcement Matters.
The only way currently avaiable to the Federal Governmet to allow the Military to get involved in any Law Enforcment Matter is by Delcaring a National Emergency and Putting the Nation under Martial Law.
Understand Now?
Hell If you want a real soloution, just put forth an plan to build Observation Posts about every mile along the borders complete with living quarters for personel and holding cells for detainees.
Then hire all these folks who are out of work and have them patrol the borders and capture Illegals and Book them and return them across the Border. Problem Solved and you eliminate the Jobless Problem.
Of course it will cost about 80 Billion Dollars and of course the Unions will immediately jump in and want to register all the Owrkes in the Democrats but hey it would work.
