I can't see anything but a few domino-like pieces to "support the structure" and a toy soldier that's posing with really stiff arms.
Agree. Unless it's a quirk of ET technology that they can only land on giant mah-jong tiles/ white plastic dominoes.
There are loads of examples of UFO-related dioramas online, posted by modellers showing their skills or just for their own/ their friend's entertainment, just like other hobbyists document their pastimes. (Click to enlarge).
Can't help but feel that for a couple of these, if someone took a narrow focus photo from the right angle and then suitably
reduced the picture quality, they'd have "possible evidence" of the most momentous event in recent history for Ron James and MUFON to
be willingly taken in by study in an impartial and scientific investigation.
We were lucky that the figures used in James' (OP) photo appear to have been largely "built from the box"; many modelmakers are well-practiced at converting shop-bought figures into original poses.
Plastic limbs can be straightened or bent with careful heating and cooling, or substituted with a corresponding part from another figure; careful filing and use of Green Stuff-type modelling putty allows joins to be imperceptible. Heads/ headgear are often easy to transplant. Unwanted webbing straps, pockets and buttons etc. can be filed down, and new ones added as required using plasticard or Green Stuff. Backpacks, webbing pouches, weapons can be cannibalised from other kits, or scratch-built, or sometimes bought as separate sets (particularly WW2 German, WW2 to modern US, British and Soviet/ Russian gear).
Green Stuff can add scrim/ foliage to helmets, hiding their origins, likewise facial features can be changed, beards added etc.
It's alarming to think that had the diorama-maker of James' photo been a bit more original/ experienced in model-making,
the source of the "soldiers" would have been unidentifiable.
Something maybe made in a fourteen year-old's bedroom on a pocket money budget would still be touted as possible evidence of US government agencies (including AARO) lying, and of ETI visits to Earth.
(As others here have noted, digital image manipulation will allow far more sophisticated fakes).
Maybe James/ MUFON will develop a protocol to take into account the possibility of this type of hoax, but I doubt it.
They are serial type-1 error makers; "evidence" which conforms to their prejudices is seen as confirmatory (or at least potentially so) regardless of source, likelihood or indeed in-evidence contradictions (e.g. the US troops with perhaps WW2 German boots and helmets). Evidence against their hypotheses is resisted, unless it is overwhelming and they realise they're courting ridicule.
This
isn't how science works (well, not testable non-pathological science anyway), but maybe MUFON's people wouldn't get on TV so often / get so many viewing hits if they were took a more prosaic view of claimed evidence.
The truth they claim to pursue might not be as exciting as they (and some viewers/ surfers) would want it to be.

Like on other threads with unidentified but probably hoax UFOs, there must be lots of possible candidates for James' saucer.
It appears misshapen (unless it was always an irregular shape). It's probably about 1 foot/ 30.48 cm diameter.
I've wondered about the two small circular bumps/ marks on the centre "disc". Maybe rivets, or injection-mould marks?
If the central disc/ dome was a separate object, it has some resemblance to a wall-bell, though most of those have a single, central point of attachment (which seems sensible).
There's the usual suspects- an old wheel-trim or battered lid from some cooking vessel etc.
We don't know it's metal; maybe a spray-painted frisbee? Well, a slightly warped frisbee?
For some reason it made me think of the underside of an old-style plastic bedpan/ commode insert, but I don't think it is.
Tried an image search, got this lid from a Kazakh website
but of course similar items might be found in the USA!

Gerry Anderson DID do a UFO series
UFO, with Gabrielle Drake as Lieutenant Gay Ellis
(sigh). Set partly on the Moonbase, in the future year of... 1980!
In real life, Gabrielle's brother was musician Nick Drake, who is much more widely appreciated now than during his life.
And I never had the courage to ask the gf to wear a metallic purple wig.
