Mehler Systems signed an agreement to acquire a majority stake in MARS Armor, the Kostinbrod Bulgaria maker of personal ballistic protection serving military, law enforcement and government clients. That firm produces helmets, shields, vests, hard and soft inserts plus demining gear, runs in-house ballistic and stab-resistance tests, and will keep its brand and leadership with group support for Bulgarian work. The purchase expands Eastern European reach, complementary capabilities, an EU supply chain and closeness to regional buyers through further targeted acquisitions.
