The above is but one military self-defence battlefield dagger disarming tradecraft primary practice
The late Col Rex Applegate, a leading instructor to the OSS in WWII, gave me a set of tradecraft primary practices for battlefield dagger disarming that went like this:
Option 1: If he has brought a knife to a gun battle, shoot him.
Option 2: If you are not armed, look for, and use a long-hardened implement and combine its use with your military primary tradecraft evasive disarming, disabling, and disposing of the enemy threat.
Option 3: If you do not have access to a robust improvised dagger disarming implement, then you had better be confident and competent in your military self-defence battlefield dagger disarming and enemy threat neutralisation tradecraft skills.
In situations where, post evasion, the enemy weapon holding hand can be seized and secured, using terrain and environment provided solid surfaces to hard impact the weapon into to cause the dagger to slide back through the enemy’s weapon holding fingers is one such primary military self-defence battlefield tradecraft skill to force a quick release of the dagger.
