The is a design of the Shinohara Heavy Industries AV-98 Ingram, specifically Unit 1 piloted by Izumi Noa, as seen in the anime series Patlabor. I intended it to be minifigure scale but is a few bricks taller than it should be.

Front view.

Rear three-quarter view.
The cockpit can open, although there is nothing that stops the top (black) section from sliding all the way out. The covers over the power train on the back can detach. The leg can open up although it is not big enough to fit in the sidearm (cannon), and the hand cannot extend in order to draw the weapon. Currently, the baton cannot fit inside the shield but this can be accommodated easily enough.

Cockpit can open.

Covers can detach from power train.
I designed a bullpup assault rifle just for fun even though there is no such weapon shown in the anime.

Reloading…
