Damn right he is
Let’s not leave out the flag bearers, creating a tempting target for any artillery or siege weapons.

tbf, artillery was pretty inaccurate - by the time it was accurate enough to hit single individuals, sharpshooters were the bigger problem.

But yeah, there’s a reason why flag-bearers have such ridiculous casualty rates. “HERE, SEE MY BRIGHT COLORS WAVING ABOVE MY HEAD? I’M WORTH BONUS POINTS”

I mean, in Roman times (the Republic, you philistine) losing a flag/standard was a huge shame. 

Later semaphores meant you could cut off communication by killing the flag bearer. Which would be beneficial in a battle  

I don’t know if any of this is true though, just facts I learned from various places and Wikipedia articles. I wouldn’t trust me on this. 

It’s still a big shame to lose your flag. Granted, these days it’s within the same military, generally the same brigade or lower. But there’s still intra military respect/shame based on your flag and who’s in possession of it.
