@Sfwmson That was the point of your rhetorical question “Do we have tanks?” If you’re planning to do something useful then good for you.
The answer to the example you gave is “No” - although the Native Americans were very effective in their insurgency notwithstanding the genocide they were fighting against.
Decolonization (including anti-Soviet) insurgencies are the frame of reference.

If you don’t arm yourself, you’re just outsourcing your protection to someone else. There is no one else.
