Also a good read on the problems with new weaponary, some things you wouldnt expect, such as Being Imperial and delivering weapoms to a metric country, tooling to work on them becomes a problem, and also the manuals on how to operate some of the equipment provided are in English, surely someone would have thought to do a Ukrainian version, it cannot be that difficult to produce.
