Today we honour the courage, sacrifice and service of all who have served in the Armed Forces – past and present. This year also marks 85 years since the formation of Army bomb disposal, whose skills we still rely on to this day. Today, and every day – we remember. #lestweforget

The #1ldteam received a visit from a random visitor this week. It is not every day you get to see a magnificent bird of prey this close however, they are used on construction sites more often than you would think. Thank you Aaron for submitting the images. #uxo #risk #mitigation
