Lion-C or -WD
Both work...
Mech carrier and BA suits in cold storage, plenty of Infantry spaces for 50 troopers to hold up, especially the -WD... heck you have enough space for a Point of Heavy BMR or two... and a Point of basic Flatbed trucks to carry cargo anywhere. There's even enough room for a single Point of standard Foot Infantry armed with Class 2 Divisor Armor and Mauser-IICs for ship defense, and techs too!
Just add a Carrier to this unit and your set to raid, just don't forget to assign an Odyssey jumper...
