1st i would grad my katana and drive down to the nearby cadet building.
Using mulitple power tools (to get into the building and stores) i would steal all the weopons,ammo,equipment and rasion packs i can find.
Next i would travel to the nearest D.I.Y. shop and take the items i need to barricade by house and made my car more of a tank.
After that i would pick up my near members of my family and take them home.
Whilst family/party members patrol the area souronding my house i would get a small group of them to help make a "tank" out of the biggest vehicle we could find.
Followed my barricading my house.
Anybody would be aloud in my house following that;

• They agree to being strip searched and checked for bites.
• They agree every think they own belongs to all of the party.
• They agree that they work and kill or they cant have shelter.

Once i have barrricaded my house i will sit out the invasion untill help comes or i have to move to another location.
