I don't own this particular set but I do own a few of HB's other German soldier sets. HB's figures are noticeably slighter in body bulk when compared to KC. Height comparisons are pretty close but HB is a little shorter. The lack of bases on the set you are asking about will only make the height difference more noticeable next to a KC figure with a base. I have found that the HB figures look good with KC vehicles but there is a definite size difference between figures, although I mix them because that doesn't really bother me. There is also a noticeable size difference in weapons, with HB's being smaller than the same weapon on a KC figure. -- Al
