In the current version of Hearts of Iron 4, we discovered a combination of mechanics that actually disables army logistics. Blogger FeedBackGaming shows how to build an army with zero supply consumption and send them on an attack without regard to infrastructure.
The basis of this exploit is a combination of the Grand Operations Plan doctrine, the appropriate sub-doctrine, and supply companies with special Ranger bonuses. With certain template settings, consumption reductions are added up in such a way that a supply of 0.00 is displayed in the division constructor. At the same time, the formation retained more than 220 attack infantry units and more than 80 organizational units. Officers with logistical skills also receive additional bonuses.
The author circumvented the limit on the number of Special Forces battalions by manipulating templates. First, hundreds of cheap cavalry units were recruited, after which they were transferred to large infantry templates. This allows you to temporarily increase the available limit of Special Forces and create three armies with 32 elite Ranger divisions. The excess infantry can then be disbanded.
In fact, the army moved through China without serious problems and continued its offensive into Siberia, barely responding to the lack of infrastructure. Even severe penalties for lack of supplies could not deter troops who simply did not need supplies. Paradox Interactive is already addressing this issue and plans to introduce a minimum consumption reduction threshold of approximately 0.38-0.40.
