Firstly, the tracks of 99A do not match the actual model. I suspect that Gaijin forgot to align the collision volume of the tracks with the model when making changes to the model earlier. The collision volume now is more outward than the actual modeling, and both sides are too outward. I’m not sure if it will make the guide wheel track more prone to breakdown.
Secondly, the collision model at the track guide wheels of 99A and 1001e is too rough and simplified. Other types of tanks can basically achieve alignment between the collision model and the actual modeling, or at least match the modeling size of each track plate with the track plate size. For example, usually 5 track plates make up 5 track plate collision models. The interval between each track shoe collision model of 99A and 1001e is half that of the actual modeling, which means that there are only 3 track shoe collision models resulting from 5 track shoes. As is well known, the more detailed and smooth a collision model is, and the more inclined the angle of impact, the more magical it is to absorb aftereffects or jump bullets. The 99A track model is basically a large board with a very small inclination angle when hit from the heading angle, and it is difficult not to doubt that this is also one of the reasons why the 99A guide wheel is particularly non magical. Only Israel’s Merkava 4 has the same problem, while Sweden’s 122 has the smoothest modeling, with 3 boards enough to have 5 lines.
