As for you not being SLDF, while the Star League did in fact create and use the classifications they are still used to this day (3049+) to describe the role function and common mech weight types of units throughout the Inner Sphere.
So instead of referring to light to medium mechs, or heavy to assault, you could refer to them as a Light Horse or Dragoon unit instead. Sure, those not familiar with BattleTech Lore will be confused, but when aren't newbs confused?
I appreciate your concern. We have quite a few people who are rather familiar with the lore of Battletech, but the purpose of this group is to be inclusive instead of exclusive (within reason). Shrouding important information with fiddly bits of lore would turn off those who aren't as versed in the source material. By utilizing easily understood (one would hope) terms and concepts, we attempt to bridge the gap between the Battletech "veteran" and "novice".
Best of luck to you.
