Available from Tommy's War is this 1/32 scale figure depicting a squad leader in BrigGen Douglas McArthur’s 84th Brigade, from the 42nd (NG) ‘Rainbow” Division which punched out of the St Mihiel salient in September 1918.
Note that its release was delayed as it was found out after painting that the figure's left arm needed to be corrected -- the last photo below shows the corrected arm position. Both left arms are included in the kit.
