Nope, they are just plain spearmen with a biggish oval shape shield, they don't throw javelins and should be less armoured than thureophoroi. And they are not "Pontic" as in "of Pontos faction", but as in "from the Black Sea (Pontos Euxinos) area" They represent a basic troop type (spearmen with relatively big, thureos-like, oval shields) common to a variety of peoples in the regions around the Black Sea. I don't think you'd want to destroy your type2 govts. just to have them.
