Correction.
My apologies to all concerned, but in my previous post I should have said
"With regard to Frank Buckles. Without in anyway wishing to downplay his service it has to be said, as he openly states in several interviews, that he did NOT serve as a combatant in WW1, but as an ambulance driver. He himself has said that he saw no combat, although he certainly saw the horrible results of the fighting."
Embarrassing to admit, but even editors sometimes fail to proofread their own words with sufficient attention.
