Soldiers no longer needed to deliver bomb by hand. It is exciting time to join the military!
Bombers are the ninth tier of Military industry. This generator is not only a significant jump in comrades, but also a large jump in production difficulty from Laboratories which were already an expensive generator. The first mission requiring bombers appears at Rank 97, and Manny Osbomb automates this industry and is unlocked at Rank 98.
Due to the bullet cost, 8 M bonus is recommended for this generator, though 2 M may be sufficient for the first few missions. For the Rank 97 pre-auto mission, 100 M - 1 B discount is also recommended for the Fortresses cost. Finally, 5 M or more comrades per second is recommended for the unlock as well as other comrade missions in those ranks. Although bomber missions don't reach the billions until Rank 111, there are high bullet missions in the 100s where building up bombers to the billions will be helpful. Although players struggling with bombers may skip those missions, there are missions in other industries with similar difficulty in ranks 97+, meaning players must upgrade their production researchers to avoid getting stuck on walls for weeks at a time.
