German-born centre-back who arrived at the Kuflink Stadium in summer 2025 having played almost 600 senior games, with nine of the last 10 seasons at Priestfield, making him the record appearance holder this century for the Gills. Ehmer came through QPR’s youth system, making his Championship debut in 2013. 

Before that, he had gained plenty of loan experience elsewhere in the EFL with Yeovil Town in 2010/11 and later Preston North End, Stevenage and Carlisle United. Team captain at the Gills from 2017, he was a permanent fixture in the side for a decade. 

He had a season at Bristol Rovers in League One in 2020/21 but returned to skipper the Gills once more after that.
