Those are not alternate, more powerful, and harder to execute strategies that the video Blueberry linked talks about.
The problem with that is that in this game everything is fairly straight forward with little difference to how it's used other than using ammo types to adjust engagement range, or boost effectiveness at close range.. all tools in the game have one or two uses at most as well.
All in all this game is a bit on the simple side and I doupt something like what's described in that video could be possible in this game.
For example, a Lumberjack will always pop your balloon and there is nothing else you can do with it, or some advanced move to excecute that will pop enemy balloons 'better' other than learning how to aim, and well as there is nothing else an enemy can do about it other than:
1. Hope your LJ gunner is horrible
2. Disable it till they get close
For the carronade it mostly relies on the pilot of the ship to keep it in just the right arc/range so you can keep them down while making it hard for them to return fire. There isn't much else you can do other than get in range and do the previously mentioned.
The enemies either:
1. Disable your gun
2. Call for help if you focus them to get the focus off of them so they can recover
I mean, I'm fairly simple minded as far as I know, but do enlighten me, is there something deeper that you can do with most guns in this game?
The only ways you can stop enemies from shooting at you are either staying out of their range or disabling their guns, that's all.
