The vehicle inherited its crew from the previous AFV, the KV-13, its 10cm main gun from the T34/85 (making it an IS-1 in effect, models 1 and 2 differed only in the main weapon). The 34/85 has been nerfed since and cannot be equipped with the 10cm gun.
I have managed to squeeze 6 posts' worth into a single weekend (besides shooting stuff with my airsoft gun). These will be distributed, 3 or 4 will be posted during the following week and the other half, hopefully with the new acquisitions, after Sunday. My weekdays will be busy as I need to finish a study about medieval executioners (perks of being a law student I guess?) so the posts are already prepared.
