Commander Revamp Patch patchnotes, https://community.companyofheroes.com/discussion/67/coh-2-changelog/p5
Ahh I thought it was reload speed and RA not movement. Still RA and damage reduction are two VERY different things. Stock and doctrinal are as well
It's just the same bonuses they get from support package in infantry commander.
No they're not. Damage reduction is very different from RA, and I don't think any infantry units should have it (looking at you rangers)
