I figured someone would bring up just assassinate the vet grens. Problem with that is your opponent will know that you will try to do that and make you pay dearly for it. Same advantage for using a soviet sniper. You know they will eventually yolo charge it with a scout car so put mines or an at gun trap and then let them get a glimpse of the forbidden fruit and they will lose a lot of manpower trying to get it. Or they will have some unit hiding in ambush but that is one less squad out there capping stuff so advantage to you again. Same goes for the vet gren squad comrade.
M15 AA half-track definitely has a nerf coming its way so I don't use it much. T-70s are pretty easy to counter with fausts and a quick pak gun which I always get since I spam infantry and want a vet pak gun for a stun shot for armor later.
"A good player won't lose his fuel to a single veteran infantry"
How can you not? Remember I said this is a match between even skilled players. They have the same amount of manpower on the field but a gren squad is vet 3 already.
We are all capable of slick play but when a commander choice necessitates that you pull some slick stuff or you lose then that is silly. The immediate unavoidable disadvantage this commander causes is what gets to me.
Going back to the flame car you say you use yes I think that would be the best way to deal with it but those scout cars go down pretty easily. This is also assuming you led with that stuff. If you don't by the time you scout a vet 3 gren squad then you are at a disadvantage for the first battle for map control.
Mmm.
You said originally that Troop Training is good because it lets you play aggressively and just push the enemy off the map. The fuel disadvantage isn't a disadvantage if you "just take their fuel". That's what I took from your original point.
You can't play aggressively and defensively at the same time. Luring M3A1s and Snipers into traps and pulling back is inconsistent with holding more than your share of the map.
AT guns and munitions for mines take way longer to hit the field than most reasonable counters to elite infantry anyways. AT guns are actually delayed an additional 25 fuel due to your training opening anyways.
If I deploy the counters and take my half of the map then I'm just ahead in fuel basically. I don't have to play aggressively against elite troops. It's the opposite of what you want to do. Elite Troops is always behind if they use Troop Training. They're the ones who are supposed to have the incredible early game. If I just stall into my superior and faster mid-game then I can just turn the game on it's head pretty quick.
I don't want to get into some sort of theory-crafting war but I will say that everytime I see a vet 3 unit in the first minute I am a-okay with that because that player will be behind the rest of the game for little gain.
edit: Basically, I just completely contend that "Vet 3 Tier 1 Ostheer Units Guarantee Map Control". It's not guaranteed at all against an even opponent.
