Gunka no Baltzar

Synopsis

Glory won over the roar of cannon fire, peace exists simply as a time to prepare for the next battle. A soldier in a militarily-advanced nation, Baltzar quickly advanced in rank. However, his career takes a sudden turn when he is reassigned as an adviser at a military school in a neighboring allied nation. Faced with little military power, untrained students, and civilian opposition to firearms, will Major Baltzar be able to win over the soldiers and civilians? (Source: Easy Going Scans)
