First line of defense would be a 70 pound unfriendly GSD (German Shepard Dog) .. If you get by her its all out war .. and am sure they would be looking to harm us !!

2nd line if they would get by Eko would be either 14 rounds of 9mm in my Beretta PX-4 Sub Compact or my Sig P229 Legion in 40 .. several others with in reach including an unloaded AR-15 with a 30 round mag laying beside it ..

Wife would be calling 911 huddled behind a brick chimney shielding her from gunfire ....
