It's a weird weight but it does hit that magic 105 number. Heavier drone alternative to the existing Blackfoot. A bit more useful weight, a lot more armor, nearly as fast, but the attribute that distinguishes it most is its chin turret (albeit with only 5 tons of turret capacity due to its .5 ton mechanism; the heavy stuff has to go to the front.)
If just the chin turret is not sufficient to distinguish itself from the drone, you could remove the drone part and make it manned as normal. That frees up 2 tons. You could use it to beef up the variants, or if you're lazy (or more accurately I'm too lazy to totally rework them in such a case), you could use the opportunity to up the armor and add fixed equipment while leaving the variants fundamentally the same; a VTOL Jet Booster (1t) + Mast Mount (0.5t) + 0.5t extra armor (probably 2 each on sides/rear/turret) ought to do it while leaving every variant intact except the E model (which runs out of space apparently. Could fix this by removing the chaff and remote sensors and upgrading the small X-Pulse laser to a medium.).

Rather than an autonomous bot, a (remotely) human-guided one. From the relative safety of home or a dropship, toss in a couple of these light-weight drones out and blow them up on something that doesn't have good ECM coverage to do 105 damage. You can also make a regular automated drone at 9 tons (with no armor) or 10 tons (with 1t of armor) that's quite a bit cheaper, but I wasn't 100% certain if those types of drones had "fly into the nearest bad guy and explode" as part of their subroutines.
A bit of a joke submission, but a lethal one.
