Like our Humvee. Originally intended as a replacement for the jeep it was not armored. It was soon armored and became a replacement for the APC.
True, but you now have the Humvee and others which are armored, but they cannot be transported by the Osprey which the Phantom Badger was designed for without the armor that would make it too heavy for the Osprey. It is not supposed to be an either or situation.
In WWII terms it is the difference between a White Armored Car towing a howitzer versus a Willys peep towing a pack howitzer off of a glider.
