I can't veto more maps, although I would like too.
Right, first you need to know that the kubel is a conscious choice in knowing that after the 5-10 minutes; It will be a combat ineffective unit and you will sooner or later lose it when the light vehicle rush comes into play by USF/SOV players(m20/t70/quad).
Second, I recommend never going mechanized against USF. Soviets maybe, but most of the time you're better off just sticking to a battlegroup headquarters. Since any vehicle rush from mechanized means you're going "all in" and if that vehicle rush fails. You will be in a very bad spot because that fuel could have been spent on getting your second truck up or even your flak truck(t3) going.
Third, I know this is personal choice, but I recommend you having these three commanders in your loadout for 1v1s:
Luftwaffe is good for getting mg34s. If you are going to get mg34s, I recommend not getting a kubelwagen and saving the manpower for more volks, or when you hit 1 cp and just callin the mg34s to act as suppression platforms.
Pop falls when a sniper is next to a building, or a damagaed light vehicle is running away and it was nearby a shack which you can send falls out of and faust-kill/criple it with.
Never bother using valiant assault, it only gives sprint and 25% more accuracy so it's just meh for 100 munitions. Airborne assault is good since it calls in stukas to strafe a cp and a fall squad at the cost of 250 munitions.
Fusiliers are extremely good with g43s. Though when getting this commander, I advice not bothering to shreck up your volks since you need those munitions for your fusilier g43 upgrades, just get raketens in place of AT. I recommend this commander in case you see sniper heavy builds or anything that excels at killing 4 man squads or smaller. Since fusiliers have good durability coming at 6 men and are the units that usually make it out alive when you hit the retreat button.
Sturm offizier is good, just keep him behind your units for accuracy boost and don't let him get shot as when the officer dies, he will force his unit and those receiving his buffs to retreat.
The other abilities I do not recommend using because they are extremely risky unless you are level headed and know exactly how to use assault arty and jagdtiger. Breakthrough's a safe pick since its only 35 munitions and lets you neutralize territory faster.
In my opinion, this is the best 1v1 commander for OKW.
Thorough salvage is self explanatory.
When you get 2 cp's, start popping JLI squads from buildings where there is heavy fighting and if it has a lot of windows, keep them in there and let them shoot at enemies. They are less effective at killing snipers near buildings but they can get the job done if they get good RNG rolls with their own G43 sniper.
Later on, you can start spamming infiltration grenades at enemies and I recommend doing so as they force your enemy to micro and potentially take massive damage/wipes if he isn't looking when those grenades fly in.
Then you have a choice of either getting an ostwind or saving your fuel for something else. If you see heavy light vehicle/infantry play; ostwind is a good choice. If not; counter with what you think is better.
The arty barrage is good, it just depends on how much munitions you have for how good it really is. Just don't bother using it to kill artillery pieces unless you are at 400 munitions for guaranteed wipes on them.
I could say more, but most of it is just muscle memory and reflexes. Keep playing and you will know what counters what and what to do if your stuck in a certain predicament, or someone else can help you out with something I didn't cover.
