It's nice to have plans and dreams. As Mike Tyson aptly pointed out, "Everyone has a plan until they get punched in the mouth." There's also the old military saying "No plan survives first contact with the enemy." As Grizz infers, people are unpredictable. So, hopefully, you have a Plan B, Plan C, Plan D, etc. Think outside the box, maybe the aggressors are using armored vehicles. The concept of wounding an enemy to tie up forces is an old one, I'm guessing it was part of the justification for going to 5.56 NATO.
