Some great work there but some issues. Like the M16A2, that would be a M16 or M16A1 and some of the colors are off on the equipment and uniforms. They are too uniform in color. if you look at any pictures from that era the uniforms and equipment was every shade of green one could imagine. The sun and washing made everything bleached out. So you might have a guy with a new shirt and month old pants that was 10 shades lighter.
I think that's the Bravo 6 AFV set, I just ordered one. It looks great but that TC(Track commander) would NOT be in a M35 guntruck, he would be more at home in the cupola of an M48A3 or M113. Best to get some books like the hard road to see what those gun truck guys looked like. They were considered a special unit with a lot of pride and did their own thing.
Most guys wore jungle boots, I'm not sure if the tankers wore tanker boots those days, those were different and when I was CAV 11D, tankers wore them. We were just told we can't anymore unless we were tankers and they took away our black berets too.
Many guys did not wear the camo covers on their helmets in Nam like Navy guys, it really depended a lot on what their commanders said about what their soldiers can do and wear. Many times they were ripped or torn and maybe it was hard to get a replacement. Most combat soldiers wore different stuff then the guys in the rear or different units and branches. That's why it's important to look at what unit they are in, were in Nam, what year and so on. Those things will dictate what and how they wear and use weapons and equipment.
Nice job on Nancy by the way.
In Nam everybody wore those jungle boots, it was HOT and humid there. I also don't think anybody would want to wear anything red for many reasons, that is a green issue towel many infantry wore around their necks to absorb the sweet and wipe their face. Also only NCOs and officers wore 45s. Most infantry wouldn't lug one around unless they were issued, all M60 and M79 gunners were issued 45s. I have seen a lot of guys with their 38s from home, some probably had a 45 or some other side arm. If they did a lot of higher ranking people would tell them to get rid of it. Most crews hid their non issued weapons from higher ups. I have read some funny stories about that. Evan I had to keep my knife in the armory and couldn't even take it to the field.
So the infantry guy needs a remake. The patch was addressed already. Plus wearing the 45 that way if he was an NCO would get him a butt chewing from some REMF officer....Ha ha ha. Plus how would he get to it if he needed to use it? Also the smoke grenade should be a different green, everything should be different greens. Also his helmet is too low, he would NOT be able to sight his M16 with a helmet that low, I know it happened to me. I liked wearing it low but when I shot I would have to raise it up and turn it around. You will see pictures of some soldiers with their helmets turned around so they can see through their sights easier. The M16 has a very high sight on that stupid handle.
I would ditch the TC and the driver who would also be more at home in a M113 or M48A3 type vehicle.
But your face painting is very good, you just need to do more research on your subjects. I have thousands of pictures I got off the internet and many more that are on web sites that do not let you down load pictures. Even going on EBay to see what worn web gear looks like helps, people sell that stuff all the time. There are some other little issues about the joining of arms but overall it's pretty good you just need to work on it, you have some skills.
