War Retreat

Alright, listen up, you chucklehead. You posted this, which means you need help understanding it. You see, a "retreat" in war is when you're pulling back, right? And a "backup plan" is like your plan B, something you fall back on when your main plan is a total disaster. So, a retreat is like war's backup plan, a way to "back up". It's a wordplay thing; get it?
