JLI > Snipers. Yeah, it's non-doctrinal, but it's better than nothing. Way better than fusiliers + they rape guards + no wasted munitions on G43's + THEY HAVE SPRINT. Volks will have infiltration nades as well from Scavenger commander.
Hans was too stubborn in his games vs Barton to do anything different, and opted to waste valuable resources on 3+ extra Flak HT's after the first one he lost. Despite flawless Puma play vs 2 ISU's, he still deserved that loss with his mismanage of resources and units overall.
Vs snipers as OKW, it's largely a learn2play issue tbh. They could use better doctrinal options, sure (like buff kubelwagon imo).
