>>6784732He pops up a lot at random, not sure what his origins are other than modern US Army but I've seen a few other poses that seem to match.
Pic related is what I've termed a "schizo army", given how many different armies and eras are represented in the poses. We have our friend the modern army marching soldier; a number of other guys from the same era, not all from the same set; a few poses from the classic Matchbox WW2 US G.I.s; a few from both the Afrika Korps and British WW2 armies. Not only that but there's scaling issues too, with some poses being disproportionately smaller than the rest. Finally, there's one pose that's especially bizarre, namely the prone rifleman at lower right. For one, he appears to be armed with a shotgun, a rather unusual choice. For two... just, that head.
