Data on the Semi Automatic Loader (SAL) they put into the M109A4BE modernization.
What happened was that as soon as the modernization of all 64 x M109A4BE was completed in 2015; they were immediately put up for sale by the (then) Defense Minister André Flahaut.
The private company that bought them in 2015 then turned around and sold them in 2022 to the UK who further rehabbed them and sent them to Ukraine.
