Given the description through the link want to say AC20 with 2t of ammo, 2 Medium Lasers, 1 Flamer, and no turret in a 50t chassis with 250 Fusion engine and 5/8 move profile with 3.5t of armor.

Personally, would upgrade that AC20 to a Gauss Rifle, those MLs to ERMLs, and the armor to Heavy Ferro, and swap out the Flamer for a Light MG and half ton of ammo, assuming availability allows. Short Ranged TDs don't tend to do all that well with Beagle probes out and about after all.

I don't have the exact specs on these vehicles. What WAS brought to my attention was that the main gun is closer to a Heavy Gauss Rifle than an AC/20.

I see, then it'd definitely need a Light engine to remain fast enough to skirmish, but that would free up 1.5t, which could go into armor and ammo which the design could really use.
