An inspection of the area has revealed nuclear survivability with multiple direct hits by use of existing trenches in which cellars can be dug for accomodation & equipment. We estimate 20 surface warheads or 3 airburst to cause very serious damage to wooden structures & three feet of concrete shelter. Most warheads can be shot down with gatling at target, airburst can be shot with Japanese S 520. Cellars should be linked & tunneled away, make your goal keeping the wooden structures. Bring targets back to life instead of leading a trail of radioactivity, be a hard case. Put tents up where the buildings were even if you don't use them, primary target the hot area.
What can happen under a tent roof here is nobody's business.
Redoubts help prevent surface strike damage, inaccurate, especially by multi Warhead ICBM because they carry charges pathetic for airburst.
You shall not hit the area mark M, it is not a W it means a lower rank of Michael in command by proxy for Archangel Michael not far away. The SIS rank of M should be W according to understanding of topographical vertical reverse. Like the up ended St. Peter's cross popular with Popes & Tarot cards.
