Richard held two things close to his heart – his daughter and his colleagues in the Army. A proud, patriotic man, he died doing a job he loved, supporting his friends.
Sapper Walker was the epitome of a true Sapper, one who would roll up his sleeves and get on with the task in hand no matter what, but importantly he would do it with great humour. He made sure that he made the most of every opportunity, both in the Army and at home; it is without doubt that he had a lot to offer and a bright future. He was hugely respected as a fit, professional soldier with a massive character. This was his first tour of Afghanistan but anyone would have thought he was a seasoned expert, such was his ability and professionalism.
Our thoughts and prayers are with his family, including his young daughter Lilly-Faith, at this very difficult time....
He added: ''I knew Richie for three years and was privileged to be able to call him my best mate. He was thoughtful, funny and a big character in any group he found himself amongst, but he always put others first.
''He was very wise and mature for such a young lad. I have so many good memories from over the last three years but the one that stands out the most for me was the day that he christened his daughter Lilly-Faith.
''He was so proud of her; that day I remember him standing that extra inch taller and his smile beaming more than usual.
''You will be sorely missed brother, gone but never forgotten until we meet again at the bar in the sky.''
