It's Diehl - the latest RBS 15 is a joint-venture between Saab and Diehl, while the pictured artillery round is Diehl SMArt 155. I also doubt that Diehl's PARS-3LR is in the French pavilion, but who knows, their cooperation with MBDA might have been a decision to move together. But their press release speaks against it - they claim there that they were in the German pavillion.
