Department of Homeland Security requests proposals to buy 7,000 select-fire "personal defense weapons". Obama using DHS to build private army?

Barack Obama: "...AK-47s belong in the hands of soldiers, not in the hands of criminals, they belong on the battlefield of war, not on the streets of our cities..." 

Mr. President, who is the Dept of Homeland Security at war with and where is the battlefield? Are DHS agents now acting as "soldiers?"

Departmentof Homeland Security Personal Defense Weapons Solicitation

From the Blaze:

IF ‘ASSAULT WEAPONS’ ARE BAD…WHY DOES DHS WANT TO BUY 7,000 OF THEM FOR ‘PERSONAL DEFENSE’?

• The Department of Homeland Security is seeking to acquire 7,000 5.56x45mm NATO “personal defense weapons” (PDW) — also known as “assault weapons” when owned by civilians. The solicitation, originally posted on June 7, 2012, comes to light as the Obama administration is calling for a ban on semi-automatic rifles and high capacity magazines.

• DHS is asking for the 7,000 “select-fire” firearms because they are “suitable for personal defense use in close quarters.” The term select-fire means the weapon can be both semi-automatic and automatic. Civilians are prohibited from obtaining these kinds of weapons. The RFP describes the firearm as “Personal Defense Weapon (PDW) – 5.56x45mm NATO, select-fire firearm suitable for personal defense use in close quarters and/or when maximum concealment is required.”

• Additionally, DHS is asking for 30 round magazines that “have a capacity to hold thirty (30) 5.56x45mm NATO rounds.”

Some interesting language in that RFP:

• "Personal Defense Weapon"? Why is it when in the hands of a civilian they call it an "assault weapon"?

• “Suitable for personal defense use in close quarters.”?? That's contrary to the White House talking points that insist these types of weapons are "more dangerous to the user" and "a double barrel shotgun is a better choice" for personal defense. 

• "Select Fire" means fully automatic capability. A great big NO-NO for us civvies.

• Magazines that “have a capacity to hold thirty (30) 5.56x45mm NATO rounds.” Also another "dangerous" item in the hands of us civilians.

• "Caliber 5.56x45mm NATO"... that's one of those high-powered battlefield bullets, isn't it?

Is Obama using DHS to "end run" the Constitution and build a private army to suppress American civilians? I'm not one to promote conspiracy theories, but that's what this deal sounds like to me.
