Say you were to have a modern day melee battle and you had 500 men and 50 horses to equip against another 500 men and 50 horses
This is the plan:
100 men- Infantry:
Weapons: Short sword, katana, 2 knives, short bow
Armor: Lightweight chain and leather
Shields: round shields.
-These guys need to be lightweight and swift, so I don't bog them down with too much stuff. They come after the initial Heavy infantry charge. I chose the katana as a special weapon because of it's killing power, handling it would require the soldier to drop his shield though. The knives are for various purposes. The short bow is given just in case a warrior can make a good shot from afar.
100 men- Archers:
Weapons: Longbows, short
Armor: chain and leather
Shields: large rectangular shields
-These guys are scattered wherever I deem fit.
300 men- Heavy Infantry
Weapons: huge spears, long swords, crossbows
Armor: head to toe knight armor
Shields: large rectangular shields
-This is the bulk of the army, not very mobile but well armed to form a wall of death. They will be split between defense and offensive roles. The giant spears impale enemies and hold back oncoming attackers. The swords and axes are obviously when the enemy is in range and ready to fight. The cross bow is also a nasty weapon that they can pull out of their sleeve to surprise the enemy.
50 horses- 25 horses will go to the standard infantry, and they will be scantly armored to allow better movement.
The other 25 will go to the other heavy infantry and will be heavily armored (poor horses) and covered with spikes.
