The RPG-43 is a Soviet anti-tank grenade, which saw action during the Great Patriotic War. It contains a shaped charge capable of penetrating up to 75mm RHA. The downsides are that it requires a 90 degree hit to do so, and it has to be thrown from a very short distance. This is easier said than done, especially against combined arms forces which are covered by infantry. The upside is that the RPG-43 is an extremely reliable and easy to modify device; magnets can be added for extra accuracy, it can be strapped to a rocket booster, the shaped charge can be replaced with pure explosives for demolition, it may be used as an IED, etc. Many of these weapons exist within Oceanyka.
