Many Evolution sets are simply reissues of LW products, and indeed this is one of them, with the vinea itself being the same as LW set 22, so see the review of LW Vinea for details. However in this case the Evolution set also includes several new figures which are pictured above.
The figures are of Romans, and from the style of costume and weaponry they would seem to be early Imperial vintage, around the first century CE. They have a mix of mail and segmented armour, but all have the Imperial-Gallic style of helmet. As can be seen there are four different poses, but beware, as LW have a habit of varying the contents of their sets, and it would seem that Evolution are doing the same, with some dealers reporting that other figures not in our sample appear in some sets. Basically, the contents of any one packet seems to be variable, so do not be surprised to find different contents to those we found in ours.
The figures are done in a very stocky style, and although their cloaks would help to explain this, still they do not compare well with the best available elsewhere. There is plenty of detail, but some of it is fairly indistinct, and some areas become quite vague such as where the hand holds the shield. The shields themselves are deeply engraved with various designs, so if a different design is required then a lot of trimming is required.
Two of the poses seem to be pushing the vinea itself. They must be doing this from inside the device as otherwise they would be holding their shields above their heads to protect them from the defenders. The other standing pose is moving forward holding his sword painfully high - virtually at his shoulder. We could see no logic to this attitude, which would in any case be difficult to maintain, and with the gladius being primarily a stabbing weapon such a height would be pointless. The final figure is a downed legionnaire, and is doubtless the most useful of the poses.
As can be seen from our review of the vinea, this is a very poor model. The Romans certainly did use such devices on occasions, although whether they looked exactly like this one is debatable. Adding these new figures does not really add anything to the model as the poses are of little use and not a particularly good sculpting job.
