By dissecting a Martian's body, we may learn a lot about their anatomy and physiology and use this data in combat.
Martians' bodies are very different from all other races we know. They are more plants than animals. Their metabolism is much slower, but they can still move relatively quickly, although they cannot dodge as readily as we can, for example. Because of their structure, projectiles do not injure them too much. The edged weapons are very injuring to Martians as well as fire damage. When concentrating, they can change the flow of the light rays around them, effectively making themselves invisible.
