Few corrections here (Aloysius and I are still getting all of this set up for everyone so bear with us)
First the banshee has two weapons, and it uses only the appropriate one for the job at hand, specifically the banshee will use the fuel rod cannon against only ground vehicles or buildings, and the plasma cannon against all other targets.
| Plasma cannon | Base DPS 90 | | Fuel rod cannon | Base DPS 60 |
| | | | | |
| 1.6x | Infantry | | 0.8x | Infantry |
| 1.2x | Heavy infantry | | 0.2x | Heavy infantry |
| 0.2x | All Infantry in cover | | 1.0x | All Infantry in cover |
| 1.2x | Covenant leaders | | 1.0x | Covenant leaders |
| 1.2x | Medium vehicles | | 2.4x | Medium vehicles |
| 1.2x | Air craft | | 1.8x | Air craft |
| 0.4x | Heavy vehicles | | 3.0x | Heavy vehicles |
| 0.4x | Buildings | | 1.4x | Buildings |
| 1.0x | Flood | | 1.0x | Flood |
Secondly the second Banshee upgrade (repeating cannon) only applies to fuel rod cannon.
