Present participle: stabbing or attacking with a bayonet, or in the process of equipping something with a bayonet.
From 'bayonet' with the present participle suffix '-ing,' creating the ongoing action form. This follows standard English gerund and continuous tense formation.
The fact that 'bayoneting' exists as a regular, teachable action in military manuals reminds us that violence and warfare generate their own specialized vocabularies—armies need precise terms for exactly what soldiers are being trained to do.
