Quick 2v2 OH tips
1. At 7 min get a pak, 2 paks if you want to go panthers instead of p4s. Pak is hads down the best antitank gun in the game.
2. Scout cars almost always do more damage than they cost. I like using them in pairs agaonst light vehicles or to kill a snared aec or t70 (hit rear armour)
3. Grens are beast with thier mg42s
4. Respond to blobs with a pair of mortars
5. Plant both s and teller mines
excellent advice here. and the spearhead doctrine is one of the best commanders, you should have no problem winning with it. OKW is a bit more tricky to play with because they will have problems with early Vickers and Maxims. typically in 2v2 Ost should always get mortar before 3 min and OKW get an ISG before 5 min. Because of the blobs these typically will always be worth it. remember to support them with Grens and MGs so they dont get killed/stolen. On maps with more open terrain, the sniper is really excellent. At lower ranks they will give the greatest bleed to your opponents manpower and on multiple occasions 1 sniper who survived has basically won me the game because of the bleed. Don't forget to use rifle grenades, they have a great range and will do a ton of damage to MG squads. You want to research T2 as soon as you get 40 fuel, then have your grens Rifle Grenade a big concentration of guys which can usually kill 3 models. If the rifle Grenades do well you can get vet 2 Grens pretty fast, remember to upgrade them with the MG42, the weapon will be much more effective held by a vet 2 squad. Against early mortar bunkers, you can build your own mortars or the mortar halftrack and drop barrages on it, Making it risky for your opponent to repair it. Unlike your mortar squad that can be retreated and reinforced once the Brit mortar emplacement is killed he just loses all the Manpower, giving you big advantage. I like Ostruppen very much vs Brits.

As soon as the game starts identify the position for your MG to protect your fuel. If its a house be prepared to put your pioneers inside until your MG arrives so the garrison does not get stolen. If you have to retreat your squads very early and lose the Fuel it can easily be game over.
