It's baffling that war photographers don't know about the dangers of unexploded ordnance — the news agencies are failing in their training.

Literal

Battlefield [to-に] go cameraman [subject-が] unexploded-bomb [possessive-の] danger [object-を] not-know [nominalizer-の][topic-は] strange [copula-だ], newspaper-company [topic-は] education [object-を] neglecting.

不発弾 'unexploded ordnance/bomb.' 戦場に赴く 'to go to the battlefield' — 赴く is a literary synonym of 行く. 教育を怠ってる 'is neglecting education/training' — 怠る 'to neglect' + casual progressive. Two blunt criticisms packed into one sentence.
