Warnings are for rattlesnakes. Bad guys advancing are for graveyards. You have to win, there’s no other choice. The door lock was the warning. Advance further the brakes are off.
From me, the bad guys will just as much warning as I give deer before shooting them...none!
Agreed. Win, period. When the stakes are life or death, a fair fight stinks. Take every advantage you can get. Attack without warning. Fire repeatedly or employ whatever weapons are available until the threat is removed, even the most remote chance of a threat. Win, absolutely, or die.
