Anno, my FiL was in the Home Guard - and said much the same thing.
My grandfather was a professional soldier who had retired in 1937 but was recalled when the war started. He was an expert on the safe storage of explosives and spent the war running a committee doing just that. 5 of his 7 sons served in the war but to the best of my knowledge only one saw active service, going over to Fance two days after D Day and fighting all the way to Germany, another was an army chaplain, so at the front with the fighting forces but not involved in direct combat. He too reached Berlin.We have a family photo taken in 1946 showing my grandfather and his seven sons, all in uniform. By then the two youngest had also been called up.
In WW1 my maternal Grandfather, his brother, my maternal grandmother's brother and a cousin died. Three of them within six months in 1915
