Page "Anointing of the Sick" Paragraph 42

Some Protestant US military chaplains carry the Roman Rite version of the Anointing of the Sick with them for use if called upon to assist wounded or dying soldiers who are Catholics.

The Catholic and Orthodox Churches consider invalid as a sacrament the administration of Anointing of the Sick by such chaplains, who in the eyes of those Churches are not validly ordained priests.

The rite performed by them is thus seen as having the same by no means negligible value of any other form of prayer offered for the sick or dying.
