@ mind
Yes axeman have disadvantage vs spearman as 2 handned axe and no shield makes it eaiy ti kill.
But know this, spear when hitting human flash gets stuck in it and it takes some time to get it out. Also spear is long, when attacked will get past its tip he can just use his sword, axe to hit the spear. It wont break spear down, but make a shock that might couse spearman to drop his weapon. Also shield is not only to block targets, it you rish whith shield and bach enemy spear whith it, you will disarm him and knock him down. I know how it is dont, once said im in Knight brotherhood and i do a lots of fights. Mostly in armor to prevent health damage, but we fight against differant weapons.
Best weapon, and easiest in use is sword (broad sword) whith shield, It has blade all over, has a tip and is good to thurst, and quite heavy to do some damage vs breastplate.
Waraxe (one handned) is good for 1 vs 1, as its heavy and it does lots of damage to shield and armor if parriet. One hit in breast plate and your down, still a life and not bleading, but your down and like where i am.
Two-handened axe - Need real power to use, as its mostly to take a swing and watch if you hit or not. Takes much strength to parry it whithout getting knockedback. In tournaments (whith wooden weapons that have led parts to make em heavy as real weapons) battleaxe man win a macth by 3 knockdown in 8 swings. Its weakness is lack of shield and axes are bad for very close distance, as its hard to use it. War axe is better in close range as you have shield to keep up the distance.
As for spear. Well i never used spear. I was using halabard (right spelled?) and pike. Pike is REALLY HEAVY and REALLY long. Like 220% of users height. Its top is big to pirce all kinds of armor and it does not get stuck in armor and human flash, but when u block it whith shield, the pike pirces the shield and gets a bit stuck in it, witch is enought for expirianced knight to disarm the pikeman.
As for halabard, its 170% of my height. Its about same weight as pike, but as its shorter the weight has smaller impact on your muscles. Its the best defansive weapon. Can be used as both spear vs mounted units and as Battle axe vs foot units, also you can pull the stick closer and have a war axe. Some halaberders had a wooden kite shield on his back, when halabardier pulls the stick back to make a 1 handened weapon, we gets that wooden kite shield and is good in close range. But to make this it really requires backup and time.
Mace is close to axe, how ever is more knockdown weapon than axe. Mace is best uned to hit arms and legs and head, not chest as it is pointles vs breast plate. Mace and axes are also limited only to chops and swings witch are easy to block (harder to stay standing). As we in brouther hood tested maces we discovered they were used more to knockdown, confuse and knock uncoucious enemies by hitting head, Break shoulders by hiting pauldrons and shoulders, break legs by hitting arm plates, and same whith legs.
Flails are the harderst to hit wepaons EVER as when you hit, enemy need only to block chain not the ball. Also you can block flail by hiiting chain whith your hand, this way you can disarm the flailman. Flail is also weak in close range. But neither do i or others in my brotherhood can actually use this weapon well.
Twohandned sword - its good only vs lightly armored As it doen not have the power as battleaxe, is heavy, hard to swing, easy to block, but very hard to stay standing. Weak in close range. Twohandned sword is best effective when you just stand on some hill and swing this sword, who ever comes near is knocked down, but 2 enemies are enough to make 2h swordsman a carcass.
Samurai weapon, well its kind of strange. If your not skilled whith it, you will break the sword at first strike at armor. You will cut through it thou. Japan weapon was made to swiftly cut through armor, and is mostly a counter attack weapon, in while yuo parry enemy attack, you contron his weapon. By controling his wepaon you control his mainhand, controling his mainhand, you may control his torso and turn him this way so he can not block whith shield and have his weapon under your control (this needs long practice and kendo dont teach this, as kendo is more a sport that war art. However when i was in Japan i was shown such tricks from Daito-ryu family line of Takeda, thou i can use them like once in every 10 tries), and what you do is just cut, katana will cut through most of armors, but try not to aim at plate but spaces betwean each plates.
I always liked to use 2 short swords, but its too hard to fight whith them. They are perfect for close range, you just use em both as bucklers, bet close to enemy and thurst through his armor. Short sword can pirce it.
Really try to use some weapons and fight whith others, see how hard and easy is to block, and how hard is to hit, not mentioning how tireing fighting is even whith no armor.
