| Sturdy | Being lightly damaged by enemy Op Fire does not cause a heavy vehicle to become fatigued (it does, however, immediately lose 1 movement point, and its armor is reduced by 1 for the duration of the activation, as per the lightly damaged effects). |
| Stielgranate 42 | If the sIG 33b does not move and chooses to attack or support an attack targeting a building, add +6 to its firepower. |
| Concussive Firepower | When a tank attacks a squad located in a building hex or pillbox, the tank receives +3 firepower and +3 range. |
When attacking a building the sIG 33b may use either the Concussive Firepower ability or the Stielgranate 42 ability, never both.
sIG 33b units do not have the Overrun ability.
