"Stolen waters are sweet" (Mishle 9:17).
The sight of a married Orthodox Jewess with a head scarves and long olive green skirt is going to arouse many of the notorious skirt-sniffing professional Zahal officer lotharios to make a move.
And given the right hormones, ambience and time of month, some of these married women are gonna succumb: that's a given!
Remember: adultery in Torah is a
capital offence for both parties, and any offspring is a Halachic
mamzer, with all that that entails! That's why
hilchos yichud and
hilchos negiyos are so strict.
Basically, Jewesses shouldn't be in a Jewish army at all. All the jobs that women in Zahal do could be done
twice as well by Haredi male conscripts.
