The Infanterie Gruppen Post
You can recruit infantry support here. The Infanterie Gruppen Post is the backbone of your army; this building allows you to call in your early support units and basic infantry units, such as the Landser.
The Ostheer use a special new way to build their units. The Ostheer is able to switch its unit-pool for different battle-situations. The building units are divided by Light Assault(LA) units and Light Support(LS) units.
That means: each building had at least three units to select from. 1 is always buildable. An upgrade switches which of the other 2 units can currently be built, switching between Pool 1 and Pool 2 - for a price...
The units that belong to LA are the MG-34 Team and the Marksman.
The units that belong to LS are the FlaK 38 Team and the Ofenrohr Truppen.
The Landser is a neutral unit, you can recruit them whatever you choose.
Abilities: Sandbags, Grenade.
Summary: Early infrantry of the Ostheer... these soldiers armed with Kar98k rifles will serve you faithfully during the match. As they use those bolt rifles they are good firing at long distance, however you can promote one soldier to Sargeant w/StG44 (Feldwebel upgrade) and it's combat effectiveness in medium range will increase. They won't fair well in close combat fights.
This unit can build sandbags from scratch. Throw Grenade ability will be available when Feldwebel upgrade is researched.
Weapons: StG-44 scoped.
Summary: The marksman wields an StG-44, has similar traits to a normal sniper except that he'll dispatch their enemies from medium/short distance and has higher rate of fire. Sneak allows the marksman to move cloaked like any other sniper, but while he's hiding he cannot fire. Remember this before engaging.
Role: Infantry Support
Weapons: 1xMG34 + 2xKar98.
Summary: This support team carries a MG34, set on a tripod and it's crew members wields kar98ks. Ideal for supporting your landsers or/and marksman(or marksmen). Let's welcome those soviets with a rain of lead!
Role: Anti-Tank Support
Weapons: 2x Panzerschreck 43 + 2x Luger Pistole 08
Abilities: Sandbags, Reload Focus.
Summary: Early AT infrantry of the Ostheer, they use the early version, the RPzB 43. Activating Reload Focus makes them shoot with more precision and reduces the reload time but decrease the speed of the unit and makes them more vulnerable to enemy fire. They must be stationary to fire and have the ability to build sandbags as well.
Flugabwehrkanone 38 - FlaK 38
Role: Heavy Anti-Infantry.
Weapons: 2cm Flak 38 + 2x Luger Pistole 08 (4 men in total).
Abilities: Fire Position.
Summary: The FlaK 38 is a light anti-aircraft weapon carried by a 4 man squad, ready to support your troops as anti-infantry support. Fire position grants the weapon more precision while losing mobility... as seen on TV! (Except for the part when it dismembered some soldiers).
Summary: Enables the production of Marksmen and MG teams. When you active LA, the FlaK 38 and Ofenrohr Truppen are disabled.
Summary: Enables the production of Ofenrohr Truppen and FlaK 38 teams. When you active LS, MG teams and marksmen are disabled.
You can purchase both upgrades whenever you want(as long as you have resources of course), but only one can be active at time.
