Someone explain this to me?

Link to Infantry patrolling what looks to be a US Town

Now I don't want to be alarmist-- but this smells funny.

If it is the US Residential neighborhood it seems to be (for a moment I thought it might be on post, but post doesn't have satellite TV antennas too often), will someone PLEASE shine some light on what is going on here?

I can see taking the troops out for a roadmarch in town- we did it in my old NG unit several times. We were even in full combat loadout, too-- except we didn't have weapons on us.

Really trying not to go all kneejerk here-- but this smells funny...
