"look after the horses [or modern substitute], look after the men and their feet, look after yourself"
A similar comment was recommended to me by my FiL who had served 1915-1919 in the Life Guards front line, it was quite succinct "Horses first, men second, officers third and last"
His other comment was "honour the dead and march on", it holds little traction in today's civvy world IMHO.
