Since my career started as an Air Force graphic designer, military artwork of any sort is my favorite type of project. I especially love doing unit logo redraws. This one was done for 3-4 ADAR, an Army unit on Fort Bragg. What they originally had was a hand drawn logo (below). The only file they had of it was a low resolution jpg so use of their logo was limited.
To recreate this logo I basically traced over the original the best I could (I use adobe illustrator) to keep it in line with the original hand drawn version. I left out a lot of the additional detail and added some spacing to the text to give it more room to breath.
