'L2P' isn't helpful man. Especially in the strategy section. You have anything more specific i'll be glad to listen to it.
As for T1: Sure, but you and I both know that T2 has to be teched up to ASAP. And Pak needs to be bought.
Which is what I do.
Which tends to leave me struggling in the AI department. Not like I get a free AT squad by teching to T2.
Thinking that you have to tech T2 ASAP is the curse of many players.
You don't. Staying in t1 as long as possible is a way to go for at least half a year now. That, with t0, is exactly where you have best counters to usf:
1. Sniper - the worst disadvantage of usf is that they have hard time countering this bastard. It also prevents your opponent from going captain tier as his only chance to win once you make that unit is trying to hunt it with m20. If you keep him bleeding without overextention you are on the path to victory.
2. MG-42 - similar to the sniper, also even one mg squad on the field often forces usf to tech nades delying vehicles and giving you chance to stay in lovly T1 tier longer. When helped with faust it can kill light vehicles in seconds thanks to vet1 ability.
3. Pios - good usage of mines win games, tellers protect you from early stuart, flak ht and m20 while creative usage of s-mines can easily wipe squads on retreat and protect snipers and mgs flanks. Early game they also make up for great building clerance unit with flamer. Later on, when your tanks arrive, you should build second squad for sweeper, capping and repair utiliy.
4. Grens - they are not as good as rifles early game but when moved in pairs they do their job, they also protect your sniper and mg from light vehicles and help capping. Later on when muni stops being a problem you give them lmgs so that they can compete with rifles. Never move your sniper forward without gren cover, he may not come back alive.
As you can see you dont need T2 before
medium tanks arrive. Pak isnt even that good against fast and mobile light vehicles as it has to reposition all the time, pgrens are usefull but hard to use correctly, 222 dies quickly and looses to every well microed usf light vehicle. HT is cool to have but also easy to loose and not worth teching just to get it. Also mind that teching t2 too early takes lots of your mp that is crucial in early game to dominate the map. The more mp you have early on the more territory you will have and deny to opponent and the faster you can get to tanks or callins. At the same time opponent will struggle to get his vehicles.
As for the maps, LaGleize and Semoisky are first to veto as ostheer in 1v1.
EDIT: Oh and I forgot about ostruppen, use some of them instead of grens early on to gain territory more quickly if you have the doctrine. They have less problems against riflemen than vanilla grens. Later on they can be used to recrew paks and mgs for fraction of the price. Mind that you shoud
never go for ostruppen -> T2 in latest patches. T1 is only 80mp and it has your most important tool: the sniper. It also gives you ability to transition into grens once muni starts to flow in.
