What it is
STANAG 1412 is the NATO standardization agreement that commits ratifying nations to implement AMedP-1.4, Edition A, the Allied Medical Publication on transferring litters ship to ship or ship to air. The STANAG itself is short: it exists to bring AMedP-1.4 into force, not to set out the litter's own specifications, which sit in the publication it covers.
Why the agreement exists
The stated aim is an interoperability requirement: an ill or injured individual moved from a ship, or from ship to aircraft, has to be transferred with the highest possible safety, minimising hazard and improving patient outcomes. NATO's answer is to standardize the transfer litter itself, so a litter loaded on one nation's ship can be handled safely by another nation's ship or aircraft. AMedP-1.4 carries the litter's own requirements; this STANAG carries no equipment detail of its own.
What ratifying a nation commits to
Participating nations agree to implement AMedP-1.4, Edition A, and the cover names no other related document. A nation's ratification and implementation decisions are recorded in NATO's Standardization Document Database, and nations examine their own ratification and advise NATO of their implementation intentions. This STANAG is considered implemented once a nation has issued the orders or instructions directing its own naval forces to put the agreement into effect - implementation is a national act, not something NATO does on a nation's behalf. Partner nations outside NATO membership are invited to adopt the STANAG rather than being obliged to ratify it.
How implementation and review are recorded
Nations report their effective implementation using the form in Annex H to AAP-03(J), NATO's standardization procedures publication; partner nations report their adoption using Annex G of the same publication. The STANAG itself is reviewed at least once every three years, with the result recorded in the NATO Standardization Document Database, and a nation or NATO body may propose a change at any time through a standardization proposal to the tasking authority.
Edition and supersession
This is Edition 2, promulgated 13 June 2013, and it supersedes Edition 1 of 22 May 2001. STANAG 1412 is available free of charge from NATO's Standardization Document Database, which is also the authoritative record of which nations have ratified this edition and how they have implemented it.
