Okay so I wanted to post this up because it is something I was taught a while ago and have found it very useful. A Marine I am close with was out camping with myself and friends one weekend and he asked if I had ever been taught how to build a tactical being Ex-Navy. I explained that the Navy doesn't have much use for tactical fires. lol
So he proceeded to show us how to build a tactical fire. He started by saying that you needed to dig a hole straight down about eight inches and a secondary hole coming in to the base of the hole from the side at about a 45 degree angle to provide oxygen. Make sure to keep all your diggings in a pile next to the main hole. You put your fuel (sticks and kindling) in the main hole and ignite it. This fire will remain lit in heavy wind and also directs heat straight up for cooking.
Now to explain the purpose for the pile of diggings next to the hole. In case of a need to quickly extinguish the fire all you have to do is push or kick the pile into the hole to to put it out. This fire is great for heating up food or water or for a small amount of heat and light.
Below is a video of a version of the tactical fire which they call a Dakota Fire Hole. I hope this article benefits someone out there.
