Sounds like fun!  Design a useful military vehicle based off one of the vehicles in TRO: Vehicle Annex.

11.   Technical Introduction (*ASIDE)(Using modular-Specialty Armor, Armored Components, CASE/CASE II for example.)
12.   Technical (Wheeled) Mortar vehicle
13.   Technical (Hovercraft) Drone ferry
14.   Technical (Hovercraft) Bomb
15.   Technical (Hovercraft) LGR Sniper
16.   Technical (VTOL) Urban scout (TAG)
17.   Technical (Small Craft) Landing Craft-Drone (Stealth)
18.   Technical (balloon city) (‘Limbo’)

Note that these are, at the bottom, light civilian vehicles, not military ones.  So, you could use bolt-on modular armor, but not just assign it like you would a military vehicle.

Next, you can make these vehicles any size, with everything up to and including Tac Ops if you want to and the rules allow it.  (I haven't looked yet, but I was thinking modular armor or armored components would toughen them up a bit.)

Finally, there is AU equipment and weapons you can choose; here's a list.

PG 182 Unique Technology, 34 pages;
  New Unit Types
    Heavy- and Assault Components (H-AC)
    Permanent AirMechs
    FighterShips
    Extra-Light ‘Mechs
    Portable Turrets
  New Construction Equipment
    Hardpoints
    Limb Extensions
    Armor Rescue Pods
  New Weapons
    Extended-Range TAG
    Cassette Missile System
    AP Gauss Repeater
    Naval Gauss Repeater
    Arrow V Artillery Missile
    Thunderbolt-TOW Missile
    Improved-Autocannons
  New Equipment
    Armor Skirts
    Point C3 System
    Enhanced-Jump Core

Since it's based off my AU, the fluff for these entries will be kind of difficult for somebody not familiar with the back-story to write, but if you want to take a shot, let me know.
