Sorry not following your point on the flag bit. It is our national emblem, we fought under the flag (as per its design of the day), the flag precedes the marchers and in my 30 years in the military the flag or a version of it was always nearby - I saluted it a 8.00 on every work day and when duty, saluted it at 8.00 and at sunset.
I think it is an integral part of our remembrance of those who served and who fell.
