I've encountered quite a few issues with this mod.
First: the m05 helmets and vests don't provide any ballistic or explosive protection. The vests are also rather ugly.
Second: At least with the KvKK reload animations, the hand animations are out of sync with the weapon animation.
Third: The single-use launchers are not single use. They seem to add an additional missile into the players inventory under multiple circumstances, and this missile can be reloaded into what should be a disposable launcher. Also, the KES 88 seems to be stronger than the modern KES 12 PST.
