Equites Clibanarii having shields?

Take a look to our standarts today. The royal guard never wear a flag into a firefight, but they use it still on queens colour.
Ok, compared two different times, but you know what i mean i hope.

I know what you mean, but standards and flags were still being used in battle into the 19th C. when firefights were happening and bullets were flying.
