This prototype never made it into full production because of cheaper($$$) versions of both mobile artillery and troop transports are still available and get the job done.
About this creation
Capable of safely firing from a great distances with deadly results this prototype was meant to be on the frontline to help friendly forces push even further forward faster. It could carry as many as 20 troops into battle not including drivers, techs, machine gun operators, and artillery soldiers.
Here you can one of the two machine gun turrets. They both have the capability of swiveling a full 360*, they can also almost point a full 90* down or up to help with both close attacks and airborne attacks.
Here you can see the rear troop access as well as the ladder leading up to the artillery section.
The artillery portion is also capable of multidirectional aiming in a full 360*. The troops are very well protected from within the heavily armored shields on either side, the only vulnerable spot is from the rear unfortunately.
Here you will see the ammunition used for the cannon.
Finally the L.R.A.T.T. packed and ready to go.... no where.
