Assuming you're asking about the reload animation, rather than the game in general, it's in the handling of the ramrod. When reversing the ramrod in accordance with the drill manuals (Literally
every drill manual, dating back to at least the French Napoleonic drill), as well as in accordance with common sense, you reverse the ramrod by simply turning the hand that withdrew it from the gun. In War of Rights, you do so by transferring the ramrod from your right to your left hand, then back.
Simply put, they added more steps into the process, and if you attempted to reload the way the game portrays in real life under fire, you would drop your ramrod. Multiple times.
They and their community then attempted to defend the choice by stating that troops would disregard the drill manual and willingly introduce complexity into their manual of arms.
It might have been amusing if it hadn't been so Goddamn frustrating. Be forewarned, the thread here has the usual War of Rights community condescension in all its glory.
