Falklands is classed as operational - pregnant is not compatible with ops and the default answer is to be sent home - the default answer since I can remember.
From another angle - how could the MoD possibly ensure the proper antenatal care for the individual when deployed? It is a part of life when non-military medical care takes the lead and therefore outside the normal deployed med centre.
Mr Hinecap - The Falklands may be classified as an operational det but the FACT that they have married quarters there, and have had for years, suggests that the 'operational' threat is deemed low. Service wives have given birth in the Falklands at the local hospital described below. The only difference (that i can see) in her being at home base and pregnant, or the Falklands and pregnant - is the classification of 'operational' to the det.
Primary and secondary health care facilities are based at the King Edward VII Memorial Hospital (KEMH) in Stanley, the only hospital in the Islands. It is a 27-bed hospital with a small accident and emergency department, an acute ward with a two-bedded intensive care unit, an isolation unit, and a maternity bed. KEMH has a full range of medical, dental, nursing (including midwives and community nurses), allied health professional staff and engineering, qualified to UK standards or recognised equivalents. Wherever possible, the hospital adheres to UK standards/guidelines for medical practice - So all good there then.
