Line-of-sight thickness
From the Multicrew Tank Combat wiki
Line-of-sight thickness is the armour a round really has to get through once the angle of the hit is counted. The steeper the hit, the more armour is in the way.
How much the angle adds
| Angle of the hit | A 100 mm plate counts as |
|---|---|
| 0° (flat on) | 100 mm |
| 30° | 115 mm |
| 45° | 141 mm |
| 60° | 200 mm |
| 70° | 292 mm |
The plate's thickness is divided by the cosine of the impact angle. Its kinetic protection and any HEAT protection are added together first.
This is why you angle your hull, and why you aim for the flattest plate you can see.
A steep hit also takes away some of the round's own penetration. See the angle penalty and overmatch.
Parts that ignore the angle
- HE and HESH ignore the angle on every plate.
- Engines, fuel tanks, transmissions and batteries are equally tough from every direction.
- Gun breeches never count as more than 100 mm.
- Composite armour is measured a different way. See below.
Composite armour
Composite armour is measured by how far the round travels through the block, and not by a flat thickness. The distance travelled inside the block is multiplied by the block's composite value. A hit at an angle, or along the length of the block, meets more protection.
Composite blocks can have extra HEAT protection on top. Top-attack EFP warheads ignore that bonus.
