I Saw the Ocean in Jaburo's Skies

Plot
U.C. 0079.12.03 - 0079.12.07, with Zeon losing their foothold on Earth, the 603rd is given a new project — to infiltrate a prototype weapon into the Federation airspace and attack Federation warships launching from Jaburo. Ensign Werner Holbein, an arrogant naval officer who boasts a proud maritime family tradition, is assigned to the Jotunheim to pilot the mobile diver unit MSM-07Di Ze'Gok.

However, the testing goes well below expectation, as both Holbein's test drop ends in failure after unable to score any hit with the Ze'Gok. On the third and final drop, Holbein manages to destroy a handful of Federation ships with a direct reentry/free descent before letting loose the attached "Kuhblume" beam scatter cannon. Before he could celebrate, two Core Booster II fighters arrived and shot down both the Ze'Gok and the retrieving Gaw carrier, killing Holbein in the process.
