Ingénieurs avec gilet d'acier

Bonjour,

N'ayant pas encore acheter le livre d'armée URSS mais les figs, quelqu'un aurait-il l'amabilité de me dire comment fonctionnent les "gilets d'acier" des ingénieurs (les figurines sont magnifiques en passant) ?

Merci d'avance

SPECIAL RULE: BODY ARMOUR
The Red Army used several types of body armour, but only the SN-42 (‘Stalynoi Nagrudnik’ – ‘steel breastplate’, design year
1942) appears to have been put into large-scale production. It consisted of two pressed steel plates that protected the front of the torso and groin. The plates were 2 mm thick and weighed 3.5kg (7.7lbs). This armour was supplied to assault engineers and to the tank riders of some tank brigades. The SN armour protected wearers from 9mm bullets fired by an MP40 at around 100 meters, which made it useful in urban fighting such as the battle of Stalingrad. However, the SN’s weight made it impractical for infantry in the open.
Small arms (rifles, machine guns, etc.) and HE suffer a -1 modifier to damage soldiers wearing body armour.
Troops wearing body armour do not increase their pace when given a run order. They can still be given a run order (to assault an enemy in close combat for example) but don’t move any faster: they run at the normal pace of 6”.

Option pour les engineers
The entire squad may have SN-42 body armour for +5pts per model

Merci beaucoup
