Fairly blah...not bad especially. Helmets seem a bit silly for a live action movie, and the red on the "trooper" is ugly. Helmetless they are just more ski-mask thugs, which we've seen a lot of in recent years.

Wondering what their designation will actually be. Vipers, Iron Grenadiers, maybe even MARS troopers, as whoever labelled them. Word is NEO VIPERS are in the film, but the shot I saw of them in costume doesn't match these.
