The mystery goes on it seems

. Sobreviviendo, I have that boat, I even separated those two men for use as figures, quite easily, and I can testify they aren't, and neither they fit with the 1/32 russians airfix, which I have and I also the scaled down versions.
The commander is actually quite well done, and in different shape and proportion. One of the men running is carrying a small briefcase with a cross on it, clearly a medic. A simple subconversion from an airfix set would be much more obvious, and wouldn't go into strange directions, as in giving a man carrying a projectile, or making the crouched man shooting to the air.
I have googled and this is the closest I have found, but not yet;

MAde by lone star in 1/32. Nearly, but not quite.
THey remind me of some of the soldiers the brand Eko made.
