This mod is a combination of both of my realistic mods (Realistic Cav vs Cav Charges & Realistic Archery Mod) 
It also adds aditional features like increasing the unit radius which gives infantry more space to fight making it look more realistic. 

------------------------------------------------------------------------------------------------------------------------------
Features 
- Archers always shoot in an upwards angle 
- Cavalry has a looser formation 
- Cavalry vs Cavalry charges penetrate more and are bloodier 
- Cavalry is faster 
- Infantry Units have a larger mass and when braced are even stronger 
- Cavalry charges are way more brutal so brace your units and deflect cavalry 
- Infantry and Cavalry have been given more space when out formation which looks more realistic in battle 
- WORKS WITH RADIOUS 
Maybe Future Features 
- Slower Combat (meaning more health) 
------------------------------------------------------------------------------------------------------------------------------
Known Bugs 

- Archers shoot straight up = Make sure you are not running ANY OTHER MOD that changes ANYTHING about ARROWS. This includes BIG OVERHAULS like MEDIEVAL KINGDOMS, AGE OF VIKINGS ETC.

Updates 

#1 
- tightened cavalry formations (still satisfying charge) 
- Loose formation tightening the formation is NOT a feature anymore. 

#2 
- All units have the same WALKING speed so when marching your army they dont break formation and such. 
- Acceleration on cavalry increased 
- Mass on cavalry increased 

#3 
- Arrows now have a spread making them less effective to people up on walls and for shooting into the frontlines(due to friendly fire) 
- Archers now have a minimum range (its not crazy) 
- Arrow damage increased 
- Archer Unit spacing changed and loose formation doesn't change the formation anymore. 
- Lowered max arrow elevation also helping against OP wall killing. They cant shoot straight up and hit people on the wall directly from above now. 
- Fixed Bug where heavy Charlemagne cav units would not run as fast as intended. 

#4 
- Elite archers have 10 more range and less spread with any bow. 
- Composite and Reflex bows now have more range and a faster muzzle velocity. 

#5 
- Cavalry Formations reworked. 

#6 
- Decreased max elevation for projectiles 
- Deleted min range 

#7 
- Changed infantry formations

If you have any features that you would like to be added hit me up, also report bugs with as much detail please. 

This mod doesn't work with huge overhaul mods like Medieval kingdoms but will work with RADIOUS.
I've also been in contact with some Seven Kingdom Total War Developers so who knows maybe they will use this mod to enhance the experience.
