On 28 June 2020, the Royal Corps of Signals marked the 100th anniversary of its foundation. Constrained by COVID-19 rules, many Royal Signals 100 celebrations were organised online, including the #100for100 challenge that involved hundreds of members of the Corps running 100 km for the Royal Signals Charity. The Princess Royal, the Colonel-In-Chief of the Corps, delivered a video message of congratulations, and the Foreman of Signals Course students successfully took a photograph of the Royal Signals 100 badge in space, completing a challenge that was set for them.
