So, we need to remain stationary for *two turns* to get the data, THEN get off the board. We're probably looking at a 2x3 space for this if I remember the hex sizes correctly.
There are 7 lights, 2 Mediums, 2 Heavies and an Assault on the board, followed up by a lot of armor on turn 9.
Reaper and Wolverine are both medium weight, with one Heavy to them, a 3025 Crusader in Reaper.
Bearing this in mind - my strong suggestion because of this is to bring at least one, possibly two heavy weight lances to help keep this going.
Our options then are:
Dragon
Bright
Skaraborg
Crusher
Dragon got thrashed a bit in their solo mission, and a same day redeployment may be hard to do for them without major risk.
I'd suggest Bright and Crusher get called in. Bright hasn't seen much action, and has a fair amount of weight to them and some speed to boot. Crusher also has some good speed and weight to their mechs, and also has a good amount of LRMs, a nice thing to have.
I'm not going to suggest Skaraborg. They were used in Henhouse 1, while in excellent repair, arrive on turn 6. That's a long time for the little guys to be holding on for dear life.
I suggest Bright and Crusher, with Skaraborg and Dragon as fallback options.
