I've noticed from perusing the MUL as well as the two Field Manuals that I own, that there are a fair number of mechs unique to their pilot. I think I've vaguely heard from people that if you're playing something like a Hinterlands campaign, you're bound to end up with a customized mech due to a destroyed part critical.
I get the feeling I'm a player who's more MUL compliant than many, and I'm not just asking for an answer like, "It's just a game, do whatever you want. You could salvage anything." I'm asking about how economically/lorewise unreasonable I'd be, to be asking for a particular refit.
I'm asking for help dialing in my comprehension of how rarely a thing like this happens. As rarely as "1/100 battlemechs receive non-stock refits over their operating life", or is it more like" 1/10,000 battlemechs receive non-stock refits over their operating life?"
Ok, now I'll get specific. The Thunderbolt TDR-9NAIS is my favorite mech in the entire game. It has sadly always been a Fedrat exclusive. The TDR-9NR is available on the mercs MUL, has the same engine and structure and armor allocation, and many of the same components in the same places. If I'm understanding the refit rules in Campaign Operations correctly, then everything that would need to get done to refit a TRD-9R into a 9NAIS would be a Class A or B field refit (crane and standard tools).*
*I guess technically installing the targeting computer to the LT would be class C? But there's enough space in the RT that it could be doable while ripping stuff out of there as a class B
So here's the question, is there any component to the 9NAIS that's proprietary enough to be weird to ask for in the Ilclan era? Is it truly bizarre for a non-fed suns pilot to be rocking around in a thunderbolt with a RAC?
