It's a brilliant way to target only combatants, and also expose them to their friends and neighbours. This attack is incredibly disruptive with very little collateral damage compared to alternatives.

And yes, it's terrorism, an attack meant to inspire terror and disrupt communication networks with a chilling effect much larger than the actual damage. However it's interesting as unlike most terrorism it does not target civilians.
