How to make flags for AFV?

You can buy fabric flags that I would think would damage up nicely.

While this describes using their decal transfers, you can do the same thing with a printed flag decal you make on your own using your printer or just a flag decal from a kit sheet.

I don't do that many AFVs, but I don't see why my method for ship flags would be different. I find a flag design I want, and then in my photo editor make a flip- a mirror image. I place them with the side where a rope/line would go butting together, then print to a thinner/lighter sheet of paper. I fold on the seam and glue them together with thinned white glue.  While it is still wet, I fold it, bend it, and shape it how I want. It should hold that shape while wet. If I want it to look very weathered, I reduce contrast, or put a semi-transparent white layer over it before printing.

That would make the flag unnecessarily thick and have you make a two sided flag when only one side is needed. He's looking to drape a flag like a tarp on a vehicle. German flags on the back of panzers for aerial identification is a common sight on tank models.

Most use aluminum foil or lead foil, old toothpaste tubes used to be the norm when they were metal. Basically a very thin but flexible and durable medium to cut to shape and then conform to the tank. Paper is often too thick and doesn't conform well. Aluminum foil can get too crinkly or fragile and won't smooth out as flat as lead foil or an old tube material.

definitely going to try out that method! thanks a lot!
