Concept 1B American heavy tank garage render

World of Tanks Concept 1B guide: playstyle, build, and tips

The IXConcept 1B is the US Tier IX reward heavy tied to Onslaught in World of Tanks. It behaves like a mobile heavy, not a superheavy anchor: you can rotate, bully ridgelines, and use a 110 mm gun that wins fights on reload rhythm instead of one huge roll.

Here is how those numbers translate in randoms, plus a clean equipment package, crew order, and consumable line-up so you stop bleeding HP in the wrong streets.

Characteristics

Use this as a quick tier check: where IXConcept 1B sits against other Tier IX heavies. Reward tanks are still rare here, so expect familiar faces from Ranked and Onslaught lobbies.

Concept 1B compared with other Tier IX heavy tanks — key parameters side by side
How the Concept 1B lines up against other Tier IX heavies.

Firepower

IXConcept 1B carries the 110 mm EXP-7. 400 average alpha is modest for the tier, but APCR/HEAT shell choice plus a workable reload still chips down anyone who tries to hard-angle you out.

  • APCR (standard): 258 mm average penetration, fast shells, reliable for quick pokes.
  • HEAT (special): 310 mm average penetration for sidescrapers and stacked effective armor.

Gun stats at a glance.

Turret traverse sits at 32°/s and gun traverse at 35°/s, so the reticle keeps up when the fight slides sideways. Gun depression −10° and elevation +20° make ridgelines and awkward crests feel natural.

Stock dispersion is 0.38 with 2.3 s aim time, so snap-shots cost you. Plan on roughly 11 s between shots, which lands practical DPM near 2,180 and keeps pressure up in trades.

Survivability

Hit points and what the armor actually asks of you.

1,800 HP is lean for Tier IX. The upper glacis holds better than the lower plate, but neither wants a hug from another heavy at knife range. Default plan: sell the turret, hide the hull.

Tip: IXConcept 1B rewards a tidy sidescrape: shallow angle, sprocket tucked, no panic swings that flash the flat turret cheek.

The turret buys you seconds. Thick mantlet and a steep roof make face-trading awkward unless they own the height advantage. Swing too wide and the long turret sides get rude quickly.

  • Roofline: steep enough that frontal overmatch is not a freebie.
  • Commander’s cupola: small and set back, hard to punish mid-brawl.
  • Side turret: showing broadside is still a mistake.

Tight city head-ons expose the hull. Ridges, soft cover, and open angles let the turret do the heavy lifting.

Mobility and spotting

Weight sits near 43.6 t behind a 900 hp engine, so you are looking at about 20.6 hp/t. Top speed is 45 km/h forward, and hull traverse around 42°/s keeps peek cadence closer to a medium than a superheavy parking lot.

Mobility versus similar Tier IX heavies.

400 m base view range is strong for the class. Camo will not save you, but vision discipline, bushes, and hard cover still swing first contact.

Equipment

Prioritize what trims bloom and keeps shells landing: rammer for rhythm, stabilizer for moving shots, vents for a crew-wide bump.

Slot Module Why it fits
1 Gun Rammer
Gun Rammer equipment icon 		Shorter reload so the ~2,180 DPM line actually shows up in real trades.
2 Vertical Stabilizer
Vertical Stabilizer equipment icon 		Tighter dispersion on the move: core for peek-and-shoot play.
3 Improved Ventilation
Improved Ventilation equipment icon 		Small pass to gun handling, reload, and view range for everyone.

Crew training

IXConcept 1B runs four crew with the commander on radio. One straightforward track:

Role 1st skill 2nd skill 3rd skill 4th skill
Commander Sixth Sense Repairs Brothers in Arms Situational Awareness
Gunner Repairs Smooth Turret Traverse Brothers in Arms Deadeye
Driver Repairs Smooth Driving Brothers in Arms Off-Road Driving
Loader Repairs Safe Stowage Brothers in Arms Camouflage

Open with Repairs across the board for lane brawls, then pivot into Brothers in Arms once the line is stable (many players swap after the second full skill). Stack vision perks on the commander last to milk the 400 m base.

Fourth skill on the loader can stay Camouflage for mid-range work. If you drop the auto extinguisher for food, plan Firefighting as a fifth safety net.

Consumables

Slot Consumable What it does
1 Large Repair Kit
Large repair kit 		Repairs every damaged module once. Passively adds +10% repair speed for the battle. 90 s cooldown; costs credits per use. Price: 20,000 credits.
2 Large First Aid Kit

3 Automatic Fire Extinguisher
Automatic fire extinguisher 		Lowers fire chance passively and auto-triggers if you ignite. Swap to food (extra combat rations) for +10% crew skills if you accept the fire gamble.

Verdict

IXConcept 1B is a flex heavy: pace to rotate, gun depression to own ridges, and a turret that covers you in frontal trades if the hull stays out of the spotlight. Randoms reward minimap readers who take high ground over ego alleys and refuse to feed flat armor.

When the hull has to work, hide the lower plate, keep the wiggle going, and force awkward angles. The mobility also helps you reset caps, plug a collapsing flank, or punish overpeeks before slower superheavies arrive.
