Vehicle Defense
Defending from within a vehicle is different than defending a home. The A Frame (windshield pillars) of a vehicle blocks the swinging motion of a long arm. Choosing a shorter weapon platform like an Light Rifle Pistol (AR-15 Pistol), Subgun, and/or Full Size Pistol. These weapons can be used inside the car with good maneuverability.
The ranges related to vehicle gunfights can vary. Find a firearm that conceals well in backpack that gives you the best survivability.
You may need other tools than firearms for handling riots or a mob surrounding your vehicle.
