Had this stuck in my head, so built them. Didn't turn out the way I wanted but they are acceptale as is I think, but these things are not worth the time and effort they take. Based on 1 cent coins, core of twisted wire with clump foliage superglued and then coated in thinned down woodglue. Messy as heck. Might add green, white and grey but not right now.
They have a decent size (20mm SandS V-100)
And I've added the grenades to every base as well:
They will come in handy for Vietnam and Modern games.
