Texas Ranger Assault Vehicle

I was cruising the net and stumbled across this, it is one of
Gary Eggleston's design concepts.It is not explained on his
site at all but I couldn't help but think it would be the ideal
Texas Ranger assault vehicle (it was the hat) ;-)

So I made a probable background for it:

In 1888 increasing Apache attacks form US territory into
Greater Texas (CSA) had caused the Texas Rangers to look
for a solution to these incursions. Because of the Apache
tactic of using mountains and sniping from that hard cover
a armored vehicle was needed. However this vehicle must
be fast and not so heavy as to lose the enemy while in pursuit,
yet be well armored enough to withstand rifle fire.As luck
would have it the French army had turned down the designs
of Professor Jean-Paul Burdin because although very fast,
they were too light in armor and had no chance of surviving
heavy gun hits. This suited the requirements of the Texas
rangers perfectly. The Rangers purchased the two prototypes
right then with orders for four more to be built in the following
year.The two were put into the field against the Apache as soon
as they arrived in Texas with devastating effect, wiping out a
party of raiders with no loss to the Rangers.
