This mod has been in development for about 5 years now. Some major features are: corpses of the fallen will now permanently stay, the population caps have been increased, new units, and also each side receives one hero unit, you can play with and against any faction. Heroes, crazy stuff (like The Maus, Powell, zombies,...) can be activated or deactivated in the reward menu. It also contains an infantry only mode, Early war mode, no pop cap mode and quick start mode in the victory conditions. This mod is only for fun! If you are looking for realism, try another one.
This video called "Man and Blood with Fire and Shells" will show you some future features from the next update of the NHCmod in particular the mini mode "Infantry Only". In this mode you will mainly only have infantry. Some light vehicles, halftracks or light tanks can support the advance of your troops. AT guns and some artillery are still available.
