Good plan, making defensive works. Defense in depth, not a “crust” type defense. But don’t forget to leave yourself a rat-hole.
A way out, I mean. Make it impossible for the Bad Guys to get in, and you’ve just made it impossible for you to get out. Reminds me of an old Drill Sergeant of mine… I asked him once why he ran us so hard. He told me we needed to be able to get out of trouble faster than we were able to get into it.
Keep on keeping on, bro..
The wicked flee when none pursueth..." - Proverbs 28:1
