So you want them to patrol unarmed?
First you say they have to patrol in armored vehicles, then when that's debunked, you say they have to patrol in body armor and with weapons. What's the point of patrolling unarmed? The whole point of patrolling is to find enemy combatants and kill them, not to parade around in their underwear with targets on their backs.
If they didn't have body armor on, you'd be complaining about how poorly equipped our troops are.
