(0005420) reyhard (administrator) 2016-10-16 12:18	which btr? unable to reproduce it on btr-80 while on btr-60 it works as intended https://en.wikipedia.org/wiki/BTR-60 [^] not sure about btr-70, since i can't find now sources about it's protection but it is somehow similar I guess 7n22 round 24mm st.3 steel at 250m = 9.6mm RHA speed at 250m - 681m/s 7n10 round 16mm st.3 steel at 300m = 6.4mm RHA (value at point blank are higher!) speed at 300m - 690m/s

Боеприпасом 5h7 и 7n10 удалось убить пассажира сквозь боковую дверь (правую, левая выдерживает), 7n22 убивает всех при простреле в любом месте под колесами. Видео: https://www.youtube.com/watch?v=6Bbnt99QBpA [^] Сейчас еще проверил БТР-80 - 7n22 вполне себе убивает пассажира за водителем. Вот еще немого информации к размышлению: http://desantura.ru/forum/forum36/topic4680/ [^] Некоторые из комментариев, конечно, на уровне слухов и домыслов, но общую картину тем не менее можно составить.

Only issue I see on model that doors are not modeled under angle in fire geometry so that might change a little bit how 7n10 behaves (yet, I have some doubts if doors are equally armored but let's don't think about it and say it has those 6mm). also, part of lower hull had 5mm protection instead of 7mm but again - that doesn't change to much since 7n10 have more than 7mm penetration at point blank 7n22 round 24mm st.3 steel at 250m = 9.6mm RHA speed at 250m - 681m/s couldn't reproduce penetration from 5n7 on any btr so beside those 2 small issues everything is working as intended - any more questions or can I close that ticket?
