Did someone ask for generic logos?? You all asked (loudly) and you shall recieve.
Most of us have some marines lying around somewhere, and one of the most fun parts of painting up a snazzy Marine Army is designing the iconography for our men. GW does a great job with their marine decal sheet, but there are all manner of other variants of the standard icons for Tactical, Assault, Devastator, and Veteran squads. Here is a logo sheet providing a set of 12 squad variant logos across a range of popular colors. I have also thrown in both roman numerals and the "Astartes Numerals" in a variety of colors.
Here is the link to the PDF file for the logo sheet you can freely pull down and use:
The sheet is designed for printout on Decal printer paper which is easily available online. These decals are designed for the CLEAR decal paper. The procedure is as follows:
CLEAR PAPER: If you use the clear decals, the decals need to be applied to a light colored surface to be visible at all. The procedure for applying the "outline only" decals is to apply them to a white surface, and wait till they are fully dried. Then using the outlines as a guide, paint in the darker color around the decal if needed. It is odd, but gets the job done.

This entire sheet is sized for Marine shoulderpads, but please make sure you run off a test sheet first on your printer to make sure.
In any case, enjoy and I wish you the best in using this set for your forces.
~Please feel free to leave comments if there is a special Chapter, Craftworld, or something else you would love to collect, but have no GW decal options, and I will see what I can do.
