Indeed it is! It's the very first Zaku II in the line, RD number 97, released in 2011. The gimmick back then was the hardpoint system, which let you attach weapons/accessories onto various spots on the figure.

Lots of newer Zaku IIs have been released, particularly under the ver. A.N.I.M.E. tagline, but the original 2011 release still has its charms.
