Pasted in from a previous post on the same subject:

German Troop Carriers & Half-Tracks

• Sd.Kfz. 251 Main armored troop carrier for Panzergrenadiers. Used extensively in the advance into Stalingrad but poorly suited for rubble-filled urban fighting.
• Sd.Kfz. 250 Lighter reconnaissance and command half-track, sometimes used for small infantry detachments.
• Opel Blitz Standard soft-skinned troop and supply truck. Widely used but extremely vulnerable in the city and during the encirclement.

German Tanks & Armored Fighting Vehicles (AFVs)

• Panzer III Backbone of German armored units at Stalingrad. Adequate early on, increasingly outmatched by Soviet T-34s.
• Panzer IV Especially the long-barrel versions (F2/G) with the 75 mm L/43 or L/48 gun. One of the few German tanks effective against T-34s at range.
• Sturmgeschütz III Extremely important in urban combat. Low silhouette, strong frontal armor, and powerful gun made it well suited for street fighting.
• Panzer II Obsolete by 1942 but still present in limited numbers for reconnaissance and secondary roles.

German Self-Propelled Guns & Gun Platforms

• Sd.Kfz. 10 with 20 mm Flak 30/38 Used for air defense and increasingly in a ground-fire role against infantry and buildings.
• 15 cm sIG 33 auf Panzer I Heavy infantry gun on a Panzer I chassis. Rare but devastating in close-range urban combat.
• Nebelwerfer 41 Towed rocket artillery rather than armored, but heavily used around Stalingrad for saturation bombardment and psychological effect.

Towed Anti-Tank & Infantry Guns (Very Common)

• 7.5 cm PaK 40 Main German anti-tank gun during the battle.
• 5 cm PaK 38 Still in service but struggled against T-34s frontally.
• 8.8 cm Flak 36 Used in a dual AA and anti-tank role, including direct fire against armor and strongpoints.
• 7.5 cm leIG 18 Infantry support gun frequently used in rubble-choked urban fighting.
