@RiflesReady, I use the same against both factions.
I want to like the Luchs. I can't justify spending any fuel for anything that doesn't have AT.
For this strat I think Luchs would be good against soviet that like to skip tech to tanks and wait for call in tanks such as Kv8/IS2. If you can force at grenades and/or T34/76 it's worth the 50 fuel as it'll delay soviet tech as well..
Same vs US that skip tech like armor doc or the doc with easy eight shermans.
To help deal with snipers Kubel vet1 ability can detect cloaked snipers on the minimap that you could arty with attack ground or barrage.
