Phones transmit signal so soldiers can be easily detected: if you see a large number of signal sources somewhere in the forest the probability is high that a military squad is hiding there. Soldiers should not have a phone when on duty.

Futhermore, if military base is located near or in the city the enemy can bring an IMSI catcher and record phone identifiers, or intercept calls.

umm I think the point is that soldiers are sneaking phones in, and this is an example of bad security enforcement within the defense services, not that defense services shouldn't be heavily regulated internally..
