Military equipment [PDF]

open access: yes, 2018
The basic weapon of any Roman soldier was a short sword – gladius. Since Roman army fought in a compact formation in which every soldier had a specific, predetermined task, there was not enough space for any individual to fight using a long weapon. A relatively small length of about 65 cm made skillful gladius hand-to-hand combat possible and also ...
