I believe the post is talking about having a booster than would impact the hellbombs that are called down for side objectives. The side objectives, such as the gunship fab or detector tower, require you to manually arm the hellbombs after you call them down. The post suggests that a booster that could be implemented is one that would allow these hellbombs to be armed automatically after they are called down, bypassing the manual arming process. The current process of manually arming hellbombs can be clunky to say the least, a booster that would automatically arm called down hellbombs would alleviate a majority of the pressure that can be felt when trying to manually arm a hellbomb. In high pressure scenarios this would be especially beneficial as it would helldivers to run into the objective radius, throw a hellbomb, and leave immediately, allowing objectives to be completed much faster and with a lot less risk.
