Each Jihadist is guaranteed to kill 2-3 enemy pieces whether they are there or not lol, i.e. he will blow himself up no matter what. Like artillery they require field spotters.

Meaning Jihadists can only be used in attacks involving ground troops as well; one tank or infantry per attacking artillery. This means, if a player wants to conduct an attack using 3 Jihadists, at least three ground units must be involved as well.

It is unknown why they cannot be used amphibioulsy.
