Of late I've been re-reading the original Battletech novels. It's interesting to consider the power and role of ASF in the novels, relative to how they play out on the MWLL battlefields.
While Mechs are the iconic battlefield asset in Battletech, it soon becomes apparent that ASF are indeed powerful and feared Mechs-busters. For example:
1. In "The Sword and the Dagger", several engagements feature ASF swooping across the battlefield, and destroying light to medium Mechs in one pass.
2. In "Lethal Heritage", which chronicles the Clans' reappearance and invasion of the Inner Sphere, a key plot point revolves around the strength of ASF over Mechs. (Phelan Kell contrives a plan specifically to draw away a wing of Inner Sphere ASF from a Clan plantary invasion.)
There are many other examples. In fact, I'm - almost - left with the question of why the Inner Sphere and Clans spend so much time fielding Mechs and Tanks. ASF wreak enormous damage on ground and in space, they streak in at NOE making them hard to detect and hit, they get in and out of battle quickly, you don't need Dropships to move most of them around, etc.
Conclusion: for those of us playing MWLL, the fiction says that it's entirely appropriate for ASF's to be hard to detect, to streak in and cause enormous damage on the ground battle, and then streak away.
Anyway, I thought others might find this observation interesting.
