Name: "Rally Defenses"
Duration: 30 Seconds
Cost: Free
Range of aura: 30
On infantry + MG -
+25% armor; +50% accuracy.
On other support weapons - +25% accuracy.
+25% armor... +25% of zero is zero so... is this literally only to buff Shock troops or is this a holdover from old CoH2 balance ideology?
Also, the ability guide seems to say that the B-4 and ML-20 benefit from the buff. I'll have to test that. Seems pretty useful if true.
EDIT: Imagine if you could stack "Rally Defenses" and "For Mother Russia". That would be pretty badass....
