OOC: we've never had one of these, so I'm curious to see how it all works out, good and bad. I've read the description and the contract entry in the rules. I still have some questions.
1. Is the contract being brought to the lance leaders IC to discuss whether to accept or not, or are they being informed that the unit has accepted the contract?
Right, you weren't there so you didn't get the head's up at the game. I mentioned that this was coming up and talked about it a bit. This contract/mission is going to be a bit more "fluffy" than usual, just due to the specific nature of it. Analysis and foresight is good, try not to overthink yourselves into circles.
Also, I did mean for there to be a discussion between players about whether or not to accept it, but it's ultimately the Unit CO's call. If you want to put a pin in "accepting" the contract and talk about it, that's fine. I haven't advanced to October yet - we are still in September what with the solos and all - so nothing has been done in AtB aside from the contract generating for us.
Finally, again because you weren't present for the talk, black ops stuff is based on your unit Dragoons rating. It has a tiny chance of proc-ing if you have a good Dragoons rating (something like 1% per contract signed), and a moderate chance if you have a crappy Dragoons rating (IIRC, something like 5% per contract). Basically, disreputable forces are more likely to get hired to do disreputable things. Since no iteration of the Rangers - or most home AtB games - ever have a bad Dragoons rating, it's not surprising we haven't seen one before. I've only ever had 2 black ops missions pop up, ever, both on an AtB home game that I deliberately ran as a semi-pirate force; ended up with an Assassination and an Espionage mission.
2. Because it's replacing mission 3, does this mean it operates otherwise like a standard mission ~ 5 lances deployed?
In general, yes. You should expect a 4-5 lance deployment.
3. Is there any intel on whether there will be innocents present? Being taken as a pet/toy points towards no wife or children present, but the possible or likely scope of collateral damage may influence responses. It's in a penthouse, who all else are in the building?
That's a very good question. The information available to you at this time has been provided. The FRR is not in the habit of deliberately targeting innocents, but they are a power of 70 worlds, reduced to 6 (one of which is a ComStar protectorate), so desperate actions are well within their remit. The Regulan Hussars are noted, historically, for their willingness to accept collateral civilian damage, along with just dropping nukes on things when they get frustrated, so nobody would be
terribly surprised if the "Regulan Hussars" committed some war crimes again. You can't make an omelette, etc, etc.
4. Any mechs that should be avoided including in the mission that are too Ranger / too far outside units found in the 2nd Regulan Hussars?
No, don't sweat that. I thought about a functional prohibition on Clan Mechs for this exact reason, but that's a whole ugly can of worms that I as the GM don't want to deal with. Imagine the local CO of this op being somebody who only has 5 Clan Mechs available.
5. Do we know what the likely strength/composition of the OpFor is or how fast the "massive enemy reinforcements" will arrive?
In general, the mission is under a turn/time limit. You should expect the likely strength/composition of the "massive enemy reinforcements" to be sufficient to have a 100% guarantee of completely and totally annihilating the deployed units unless they de-ass the mission area in time. Essentially, don't dawdle. Should be become necessary to actually deploy said reinforcements, I'll start with Bryan's double-binary of Dire Wolves and go up from there.
In terms of the immediate defenders, as a logistics center, trinaries would rotate in and out of the area taking on new personnel and supply, so an accurate prediction more than a week ahead of the op is basically impossible. If you accept the contract, you'll get a standard OPFOR writeup just like a normal mission. Since it's a base, you should expect some degree of base turrets and civilian units. Since this is an extended operation near a major operating center, you should not expect to have artillery support (out of range) or much air support, if any. From my one previous experience with an Assassination scenario, you have very good odds of this being an airdrop, which means ASFs are needed to escort your DropShip in and out.
6. If taken and there's a success, is the salvage of 1 mech/lance rule - only for the deployed lances while the two random bonuses with a reroll apply to the entire (active) unit?
Every lance in the unit gets the random bonuses. Every deployed lance gets to "drag back" salvage.
