Reddit reviews Fighting Techniques of the Ancient World (3000 B.C. to 500 A.D.): Equipment, Combat Skills, and Tactics

So I decided to dig out my Fighting Techniques of the Ancient World book today because of something I saw in r/askhistorians and I saw something that made me come back here. On page 108 it says "This Roman auxiliary cavalryman was equally capable of fighting dismounted as he was from the saddle. He is armed with a spear as his primary weapon, but if dismounted he fought with his spatha. The spear was mostly used overarm in battle. His oval shield allowed him to fight dismounted at no disadvantage when facing conventional infantry. It was made of wood with leather covering, and a metal boss..." I would guess that we will see dismounted troops, but they'll use secondary weapons on foot.

This is one I enjoyed reading, the series as a whole is a good generalized coverage on warfare throughout history. The book is divided into chapters covering different aspects of warfare (infantry, cavalry, siege, naval, and command).

Well, that would vary greatly battle by battle as there considerable variables to take into account: Terrain, combatants, technology, etc.

You may be able to find some answers if you narrow your scope to a certain period/region.

A book like this may help you. It demonstrates fighting techniques and certain battles (step by step) and how they were fought and how the victors won.
