Jerry, Don't listen to these guys.....They've been sniffing too much of your crinkle-coat dust lately.
I haven't worked with recent versions of Corel Draw, but will give you what I know from a pretty old version.
Basically you are looking to convert a bunch of dots (raster data) that your scanner outputs into a bunch of mathmatical data describing boundaries and fill-colors (vector data) that Corel Draw uses to approximate the image represented by those dots.
Your scanner output is probably a raster file format like .jpg. You can import the .jpg scanner output image into Corel Draw. Once you've got it imported, Corel Draw has a conversion function that does the process of raster-to-vector conversion for you. Depending on the complexity of the raster image input, the conversion could take quite a while (half-hour or so for even pretty small files on the slow machine I worked on at that time). However, military insignia are pretty simple graphically speaking -- just a few colors laid out in fairly contiguous fields/areas.
NOTE: the vector output of the conversion on the older version of Corel Draw that I worked with usually needed a lot of tweeking to make it accurately reflect the raster image that was converted. The difference created by the conversion process was simply a matter of the conversion function needing to make a series of "best guesses" as it progressed. Those best guesses would each be off by a bit from the original raster data and, after a bunch of such guesses, the accumulated error represented a very noticable deviation from the original image.
Once the Corel Draw internal conversion is complete, you can save the vector data into whatever output format Draw is capable of creating.
There are also software programs like TraceArt or RasterVect that specialize in this type of conversion (raster to vector). But the time invested learning a new program that you'll use once (or even just occasionally) is a tremendous waste of time that could otherwise be spent depleting your CBL stash.
