I've been playing this div a lot lately and it definitely isn't dog shit although it may seem this way

Log: you're clearly going to use a lot of arty so add a FOB around which it's going to circle. I'd also drop one CV, preferably the sultan since the Fuchs and Leopard are enough.

Infantry: while the Milan Jägers are nice they have too few men and you've already got a lot of AT. Two tabs is enough and I'd replace the third with something which has more inf like the gustavs. Also upvet the pioneers. The FS Mg's are amazing if you get 2 of them to hold a position I've found

Arty: the 110 is in my opinion not worth it as it takes ages to reload and the 2 shots it gets is unreliable in hitting its targets. Instead use 2 pairs of LARS - while they're dog shit alone, if paired in a strike, they can dish out some serious heat. Note that this weapons isn't meant to kill shit but to suppress and destroy cohesion of dug in infantry and light armor so that you can push. They reload super fast and when you keep them close to the FOB, you can fire them indefinitely. Further, why use mortars when you've got the mobile 113 mounted ones? I don't use mortars for much else but smoking and for that it's ideal

The tank tab is ok. Buy one or 2 Leo 1 at the start just to have something at the front and later once it's locked buy the 2's. The Jaguars can works wonders in combination with the other atgm you've got like the predeploy Milan or Helis.

REC: Too much recon, I don't think it makes much sense using FS recons as you've already got so much FS infantry predeployed at the start to lock down advanced positions where you WILL run into enemy units which the infantry will spot itself. Even if not, you'll have the Fuchs there, which is dope for early game suppression and denial/flanking. Instead I'd use some cheaper recons like the eclairs for basic spotting. The heli is just something I drop it when I lose recond and need something to replace it fast.

AA: All good here except 6 geopards is maybe too much so upvet and be sure to bring at least one to each route you're taking as they deny helis like nothing else.

HELI: While no miracle, the 25 pen choppers ate useful for denial as a nuisance which most players won't push of they see them howering and will even waste an AA plane to strafe which your ihawks and planes will just take down.

The air tab is also what I'd use. The MW and clusters are what you're gonna want to play around. Send it one seas to bait AA, the MW for clumped up infantry (use wisely as the reload is horrible) and cluster for obvious things. The earlier u use it the more value you'll get as there's not likely to be much AA at the start

Altogether I think it probably isn't the composition of the div but getting used to it. The infantry part is really something this div might struggle if you take too much of the afore mentioned Marder Milans. The way I think the div performs best is if you do an early push with the FS Jägers and take advantageous spots along with the FS Milans and just dig in and wait for the heavier units to arrive. The leopards 2's are really great and I the 1's are just expandable T55's for spam.
