Let’s say that you’re tasked with creating a defensive line capable of defending Moscow from attack from the west. Your enemy has access to a million poorly trained soldiers, as well as laser artillery pieces that are powerful enough to turn rocks into plasma in seconds. You have access to around 0.7 million, and you can only use weapons that don’t contain advanced electronics (i.e missiles and jammers). How would you go about doing this?

This is for my fanfiction. Somebody needs to design the Kirigiri Line, and I know I’m not doing it.
