Reading all the posts, it seems that could be a difference between the experiences of women military in US than in Europe?
In Spain the women could serve in the military and also in combat duties, in fact some women are even enlisted in the Legion, that is one of the elite corps of the Spanish Army, in fact Idoia Rodriguez a soldier of 23 years was the first spanish woman died in military action in the history of the army when she was killed in action in 2007 in Afganistan.
It seems that more or less serve with great will of acomplish their duties, and as showed the death of Idoia they was prepared to go to risky missions.
Also we should think that women has served as militaries or warriors in differents cultures: Artemisia of Halicarnasus leaded personally her fleet in Salamina, Boadicea commanded her troops personally, the female scythian archers were famous in the ancient times (and in part the basis for rumours of amazon kingdoms in zone of Ukraine), the celts seems that permitted the women serve as warriors, there were other examples, in some case exceptionals giving the athmosphere of the times when they happened but that show that at least the women could serve as soldiers:
http://en.wikipedia.org/wiki/Timeline_of_women_in_early_modern_warfare
the example of Idoia, the facts showed by Arctic Warrior and Redbeard, and we never should forget the example of soviet women in World War II:
http://en.wikipedia.org/wiki/Soviet_women_in_the_Great_Patriotic_War, in fact we would not need any other argument seeing the facts about the use of women by the Soviet forces to doubt that the women motivated and with the will to accomplish their duties with great will could clearly serve in practically all the combat duties during a war as good as their male counterparts.
Respect to the examples of the ROTC, I don´t know if this is caused by some kind of cultural differences between US or Europe, although I think personally that I agree with Arctic Warrior:"You guy's seems to be pretty bad off then - being a leader you have to identify what the problem is, if they can't or won't do this or that and then report sick - make them do or quit!
That has nothing whatsoever to do with sexism witch-hunt this is leadership!!!!!!!!!!!!!!!!!!!!!!!!!!!
If those women have some problems monthly or whatever; adresse that problem to solve it - they knew the conditions when entering said service, didn't they??? But don't as a leader tell me, I suspect - talk to the person, get a picture of whats the problem and solve it in some way...
"
And returning to the point of causing a far more presence of women in World War combat duties, could be we nee a POD before the World War II, I was thinking and also with the information proportionated by another posters of this thread I made this some kind of brief TL:
Caused in part by the presence of special women units in Russia during World War I (as indicated by Merry Prankster) and the fact that Stalin dies during the fight for the power against Trotsky, Trotsky is the now leader of Soviet Union, based in this (and I confess I am guiding with personal instinct about the World Revolution and the equality showed by the soviets in treating women and men equal at least initially) and the presence also without the stalinist purges of some women in interesting power places like Alexandra Kollontai, there is some effort to experiment with women in some combat duties (an earlier formation under Jan Alaknis of experimental air combat units under Marina Raskova), the fact of this World is that Trotsky after the failures of the attempts of made a revolution in Germany in 1933 against Hitler (only reforcing the position of Hitler) an disilusioned and weaken by the failures have to share the power with Bujarin, (no purges against the militaries because no Stalin).
1934 sees the bombing of the belgrade parliamen with the death of Alexander I of Yugoslavia (this but causes the survival of Barthou).
1937 Crisis in Rhineland: the little war between Germany and France is followed by the intermediation of the United Kingdom by a treaty that permits the occupation of Rhineland by german troops in exchange with the demilitarization of the german frontier with Belgium and France.
1938 Nazi coup in Austria and a quick invasion of 5 days surprised alls including Barthou and Mussolini. Anschluss with Austria (at this time Neville Chamberlain goverment considers so dangerous the attitude of Barthou and Mussolini respect to Hitler than the Hitler agressive position, there is a clear british neutrality)
1938 october: blitzkrieg in Czechoslovakia, in 20 days the czech army collapses, there is a hard resistance and important losses in german army but at the end the czechs suffers the first real show of the blitzkrieg, France with all the time need for mobilization not could intervene actively except some minor skirmishes in Sarre with Germany, Mussolini that expected a quick reaction by France (the fortified Brenner Pass was too much hard for italian troops to try to pass and Mussolini expected first a great french offensive to according to the pacted with Barthou go against the germans) is enraged by the slow mobilization of France and clearly from this adopts a neutral position in future european affairs (he maintains but a personal friendship with Barthou).
Dimission of Barthou.
Hitler annexes Sudetenland while Slovakia is proclaimed independent, Chamberlain praises the moderation of Herr Hitler when he decides to permit czechs remain independents.
1939 April Annexion of czech lands by Hitler: Chamberlain suffers attacks in the parliament for permitting to feed this wolf that seems to want to eat Europe. Crisis in the Daladier Government, substitution by Reynaud, return of Barthou to the Foreign Affairs, substitution of Gamelin (accused of fiasco of France during the Czech War) by Weygand, Bilotte named commandant of the new Armee of Metier Français to counteract against the panzer divisions that in Czechoslovakia showed the new style of war. Pact between UK, Poland and France (Italia is invited but refuses because Mussolini not believes that the West could have a real will in treat with the germans, he but offers secretly to Barthou all the economic and diplomatic support of Italy to France in case of war against Germany)
The Soviet Union that by this time has a less massive army than in OTL but more modern and profesionalized and well leaded has also two air regiments of fighters and one of bombers manned by women and some little experimentation with some reluctance by some soviet officers are leaded in creating soviet tank units manned by women.
20 August 1939 Hitler invades Poland. Soviet Union proclaims his neutrality (Trotsky believes that this war is war between capitalist potences and so on it is better to see the capitalist destroying themself, also the Soviet Union is at the beginning of the Nipon-Soviet War of 1939-40 -where the soviet women pilots perform a good role in fighter missions- Neroon idea).
2 october french forces occupies all the Sarre after hard resistance.
16 october: last polish resistance defeated
March 1940. Forced by the presence of considerable forces in the allied side and also because in this ATL not count with the soviet help to provide raw materials, Hitler needs to end definitively and quickly a campaign in the west (no Scandinavian campaign), accepts Guderian plan (in the other side french after the Sarre campaign have a lot of positive thinking in battling the germans: sadly because this -too much proud- Breda variant is chosen).
April-july 1940 the fall of the West: Guderian forces smashes french-british forces. May: Disaster at Dunkerke: a lot of men and equipment are lost (Derek Jackson idea, effectively BEF is more or less almost wiped out, Bilotte and De Gaulle but have could made an ordered retreat of french units -little french units are present in TTL in Dunkerke- to the line of the Somme)
Fall of Chamberlain goverment. Churchill government begins: he says that UK is prepared to fight until the last man, Barthou and Reynaud indicates that France is prepared to fight also until the last man (in TTL the frech suffers far less losses than the british because almost any frech unit was trapped in Dunkirk).
July: evacuation of French govermment to North Africa.
Hitler decided to press the seemed weak link of the allied chain : UK, Hitler indicates that british have been victims of the lies of the french like Barthou and Reynaud and mad and proud men like Churchill in a war against the nation that should be his naturall ally, he offers peace to Great Britain, this is refused by Churchill and the coalition government of UK.
Beginning of the Walkyria Operation (the pression against great Britain) massive operations against airfields in Great Britain: the Battle of Great Britain has begin, british receives support from frech air units transported from North Africa, but they suffers a lot, they need use women pilots early to use to transport new fighters to the airfields, in one of such ocassions women pilots engage german fighters, they performed more or less well, and having a great need of pilots, reluctanctly is decided to experiment with this, Churchill is not a great enthusiast of the idea but the example of soviet women performance in fighter missions in Soviet-Japanese war of 1939-40 and the desperate situation obligates to made this decision.
August 1940: that terrible sea mammal begins when the germans try to invade England after weakening the air defenses of United Kingdom, during 72 hours it seems that some kind of miracle could be get but then appears the Royal Navy and the French fleet and in the battle of Channel send to the most part of the Kriegsmarine to the bottom of the sea (Italy neutrality -and in fact economic support to France- permits move men, ships and equipment to confront this invasion also some frech units are active during the two weeks of campaign against german invasions) the experimental Squadrons "the Eagles Ladies" and "Ladies of the Skies" performs reasonably well, in fact performing a lot of risky missions showing a great will in fight german fighters -Churchill would say of these women: "these ladies could be mad in making these missions, but it is no doubt that if this is madness I think that I begin to like this kind of madness" -
The defeat of the Kriegsmarine mades of the Luftwaffe the only way to get provission for the isolated german units in UK but without any reinforcements and the fact that now the british airforce is beginning to recover made of the two weeks of land campaign in England practically a long agony for the german units.
Caused by the failure of the Walkyria Operation plus the example of soviet women in the air force (also a experimental tank battalion only manned by women has been forme at this time in Soviet Union) mades the pression by Hanna Reitscht get part of his objective: the creation of the first experimental squadron of Luftwaffe manned by women -but ony to special missions like transport commandos or escort personalities-)
In the UK the succes of the women experiment and the propaganda about these ladies permits to consolidate the presence of women in combat roles as fighter pilots.
.......................
And well I think that with this we have the beginning of a more active participation than in OTL of women in combat units in this ATL World II (surely will have a barbarossa operation with important roles for soviet women and could be even with the time german women fighter pilots)
