Yeah, those GI's uniforms woulda been a dark brown semi-gloss/satin from the water, and about the only thing right on them is the web gear & leggings... Definately not Army uniforms, as was already pointed out. And not near enough gear. Every GI was weighed down with packs filled with rations, ammo, water, ammo, ammo, and ammo, mortar rounds, TNT, grenades, gas capes & masks, life preservers, and, oh yeah, ammo... Bandoliers everywhere... Most of those guys waded in neck-deep water initially if they didn't sink to the bottom, first.... That cloth helmet cover on the one GI is a distractor as well... A Pacific Theater beachhead would be a better dio for the stuff used... The Sherman is, well... ALL wrong... Just out of curiousity and don't take this the wrong way, but does this guy, Art Instructor, ever READ here? Seems that these types of errors are the norm, rather than the exception... I mean, all one has to do to research these days is point & click (or in this case, watch Saving Private Ryan for about 5 minutes), and everything you wanted to know about everything is right there... (I wish there was such a thing as the internet 30 years ago, when I spent hundreds of dollars on reference books) I'd think he'd be getting the message from the feedback by now, lol...
I apologize if my tone comes off as some kind of "authenticity Nazi", but having been an Air Force brat, career US Army NCO and a WW2 re-enactor, it's the cross I bear... (My wife suffers through my watching war movies and TV shows and howling at the TV screen about inaccurate stuff all the time... "Can't you ever just watch a movie?" is her lament...) Hollywood drives me nuts at times... Hell, I'd do the military technical advising for free if they'd just do what I told 'em to... (Not really, but I'd work cheaper 'n Dale Dye, I reckon..)
Overall, the models themselves are well done, but the authenticity errors outweigh the pluses...
