Not much to be said about these, they are Spanish and are quite common. I like them as they are all marching poses and will make nice displays. Originally made in polyethylene by
Reamsa they would go on to be sold under the
Soldis (soldier) label by
Gomarsa in a PVC type compound, which could be a vulcanised rubber like the
Texido figure Brian identified the other day.
[Major re-write after comments, some of the less well painted ones may be Reamsa]

These are all presumably Naval figures and are the later
Soldis mouldings in the rubber-like material, nearly all the figures march-off on the right-foot so can follow each other across the mantle-piece in step with each other!

Naval figures in Summer uniforms to the right and a couple of Air Force (?) figures to the left. These all seem to be late ones.

My favourites, the Spanish Legion and a lone Frenchman, they all seem to have a Spanish
CETME assault rifle, which is a tad anachronistic for a Foreign Legionnaire!

Two military types and two of the Spanish Gendarme (
Reamsa originals?) with their distinctive hats. The policemen are - needless to say - marching-off on the other foot...something that anyone who's ever done a large parade involving police units will know is par for the course!
