I'm attempting to create a famous bradley that served in my troop during the invasion. any tips in painting on the numbers would be greatly appreciated

First off, Welcome to the Big "A".....

By numbers, I take it you mean the bumper numbers? Or the tactical numbers on the sides of the side skirts? IF the bumper numbers, I would look at other kits decals that could be scavenged to cobble them together. I am doing the same thing with the Bradley I commanded with 3 ACR and had to build my bumper numbers. The tactical numbers were easy to mask and paint. I have a ton of extra decals, that I could go thru to see if I could help. What are you looking for specifically? Thanks, "Q"
