M247 Sergeant York provides a compact example of a military programme that looked plausible on paper but behaved disastrously in testing. The account jokingly recalls the system trying to engage a portable toilet's ventilation fan and then slewing toward the senior officers observing it. The anecdote makes sensor discrimination and integration, rather than gun calibre or rate of fire alone, the decisive problem. An official programme and an expert design team do not guarantee an operationally reliable weapon.
