120 munitions for something that gives you full map control for 45 seconds? Wow.
QFT.
This commander is a guilty pleasure, although I don't think it shines in 1 v 1 as much as bigger games when it's a complete win button (just played a 4 v 4 where two Opels allowed me to spam 2 Tigers. Cheesy? Sure. Fun. You betchya!).
Given the fragility of the Opel, though, in 1 v 1 it's very vulnerable. A lone M3 or one squad of scripts can take it out easily.
But, yeah, that Stuka cover is awesome, I'd raise it to 200 munis so you use it more selectively.
