Thank you for the research Failure! Combined with what I've learned so far, and Arkansas Warrior's input, I feel like I do need to change the overall profile.
And yes indeed Failure: giving the right feel of the unit (along with sense of playability interest for me) is what I am shooting for.
Fat Guy, I was reading the fluff on Catapult's Sarna entry, and then cross checked SSW's availability list up to 3028, but there is consensus here with regards to TRO3025, so I'm good with that. Also I now notice it as rare but available on xotl's Faction Assignment, Kurita 3025 tab. I'd be happy to find a way to include a Catapult; love them.
Looking at Paladin's work (thank you for the time!), all of these suggestions seem to fall into place. This line up gives us 2 recon lances, tighter integration to the battalion command lance and the assaults, a couple of premiere units, and makes use of mech variety.
I want to think on this composition. I was starting to get used to the idea of almost unified movement profiles across each lance, and I see some lances where there is more variability.
Work calls, so I likely won't be able to add more until say Saturday, but still have my ears open.
Thanks all!
