The sig line is reserved for quotes and military resume' (Unit, dates, etc.). Do not post images (jpg's), movies (gif's), etc. in the sig line. We don't want to look at a picture of your rank, your badges, a cartoon, or your wife's breasts (at least not in the sig line).
If you are/were a Ranger, your RS Class number, Unit, and dates served need to be in the sig line. Future Soldiers need to have their shipping date in this area. Mentees should have their Mentor's name in this area.
