The detail on the individual Conventional Infantry is not very high as they are VERY small. In my opinion, it doesn't really matter. Battletech isn't big on
WYSIWYG as it is.
Here's a perspective shot comparing it to a CGL Locust from A Game of Armored Combat, a IWM Elemental,
Roc Protomech, and Badger tank.
Front line has 3 of them (I can't remember which is which) on one base, 3 individuals with an APC to represent Mechanized Infantry, and a Track Bike for Motorized Infantry.
I put them on a 3/4" disc to make them easier to share a hex with a Mech, Vehicle, or Protomech. I was inspired by the size by the Protomechs having a similarly-sized base, and the Battleforce base that the Badger is on. And the disc technically isn't a problem for Infantry, as they don't have Facings for direction of attack or for getting hit.
