how does this thing explode? and how do u activate it?
TimeSan, it is a Soviet 85 mm APCR shot. It has about 175 mm penetration against flat armor but it does not give you big advantage in real battle because you hit sloped armor most of time. Overall, APHE is better because it deals more post-penetration damage.
Its an subcaliber anti tank shell. Though in my opinion the core should be tungsten instead of quartz.
