Eagles cum cuckoos . . . .
but it is concepts like freedom/nation/home/religion that:inspire people (rightly or wrongly) to fight not a piece of brass or cloth on a pole - that is just a symbol, something to focus on because one can't see the more important things.
As an ex-serving soldier I regard your comments as insulting. It is clear that you understand nothing of the concept of, in the case of the British Army, 'colours', or in the case of the French - 'Eagles'. What is bound up in those "pieces of brass or cloth on a pole"
is the remembrance of those who died for the "concepts like freedom/nation/home/religion",
and I hasten to add Regiment and comrades.
Emblazoned on British Army "pieces of cloth" are the battle honours in which a regiment fought and with them comes the remembrance of those who died!
Even today - Queen's Colours and Regimental Colours are highly revered and, quite rightly, when those colours come to the end of their life they are laid up in cathedrals, that those who died in the service of the regiments, will never be forgotten. Also so that you can continue to enjoy the concepts like "freedom/nation/home/religion" which their death has given you !
