None/Calm/None.
2 rerolls left.
Also, thought standard infantry were limited to being on base for base defense missions?
Also, not seeing a record sheet for our anti mech jump infantry with blazer.
Right, so normally you have to assign units on a weekly basis. The problem with doing that is that a mission which comes up like this comes at you with LESS than a week remaining (so you can't - technically - shift units around), and without being able to use infantry or BA it's an auto-loss, and that's shitty game management. So I'm allowing you to freely shift units around prior to this game in order to make the objectives work. The general campaign rules will remain the same, but when a mission like this comes up where it's an auto-loss if you don't have a specific unit type, I'll be more flexible about unit assignments.
Also, that probably means that the local CO should consider how he's planning to get infantry/BA to the building. Right now, AFAIK, you have a Maxim available, and BA can ride on OmniMechs. That second point might influence reinforcement choices.
Finally, the 3rd Ueda Jump Infantry template is from TRO 3085, but there might not be a canon record sheet. As such, it's literally a 21 man jump platoon which deals 14 damage at max strength (13 from the blazers, 1 from the single heavy support laser), and loses 0.590 damage per man killed (rounding up); 1 foot or 3 jump MP, no additional armor divisor, and has a short range of 2 hexes, medium range of 4 hexes, and a long range of 6 hexes. That should be enough for a hand-built sheet.
