The Soviets have at most 2 armies in Germany, but they are infantry based and have only 2 tank divisions, and are deployed in a defensive posture - from the Soviet Operational plan quoted earlier.
The GSVG in 1948 have 5 armies. You may be confused because the Soviet armies were normally echeloned so that the two you mentioned, the 3rd Shock and 8th Guards, were up front. Calling them infantry armies is a gross oversimplification: while each army may have had “only” one tank division (which represents more tank divisions then either the British or Americans have in Germany), this ignores that their rifle divisions had recieved organic tank regiments of 52 tanks and 16 self-propelled guns and had been subject to heavy motorization, with the average number of trucks rising from 100-per-rifle division in 1945 to almost 1,300-per-rifle-division in 1948 (
The Development of the Soviet and Russian Armies in Context, 1946–2008, Page 223). A better description for them then would probably be “semi-mechanized” armies. As for the other armies, they constitute a tank army in the second echelon and a pair of mechanized armies in the third which between them had 4 tank divisions and 4 mechanized divisions.
South of the GSVG, the Central Group of Force's in Austria and Czechoslovakia constituted essentially another mechanized army, with 3 mechanized divisions and a rifle division. In the "shallow" strategic reserve in Poland, the Northern Group of Forces constituted two armies, with four tank divisions and a number of rifle divisions. Finally, the Group of Force's South in Hungary and Bulgaria... has technically been disbanded in theory. In practice, it's functions had merely been passed on to another mechanized army.
So altogether, Soviet Forces in Eastern Europe had 9 armies or the equivalent there-of. The defensive echeloning of these forces does preclude the Soviets going full deep operations on Day 1, but the Soviets by this point are extremely skilled at rapid maneuver and redeployment so it should only be a matter of days before the German, Central, and Southern (against Greece) go over to a full-scale offensive, which is practically no time at all. The two Northern Forces armies will be there in a week. The first waveof reinforcements, which would be multiple armies with dozens of divisions, would be arriving from the USSR by the end of the second week. These are extremely small time-scales in the strategic sense...
Although those countries may remain neutral the Allies, especially Britain, have military bases in the region including RAF bases in Iraq and it is unlikely that they will be stopped from using them. Technically Egypt remained neutral in WW2 until February 1945.
Britain had fully pulled it's military out of Iran by the end of '46 and out of the rest of the Middle East by mid-'48. Only observers remained by that point. Even if their bases had remained, it is entirely likely they would be stopped from using them: can't use a air base if a Soviet tank is parked on it's runways. Even before that, these bases had little in the way of air defense and would be vulnerable to Soviet counter-airstrikes.
The French evacuate their force from Berlin? this is new to me.
They stay and even build a new airport:

General Jean Ganeval lead the french effort in Berlin.
I have the French informing the Americans they were pulling out shortly after the blockade began. Maybe they reversed their decision when the airlift started.
In 1949, the french army were not only Gendarmerie, French army was able to send troop in Algeria/Indochina, it was not so well equiped (even Panther tank regiment!) but it wasn't a gendarmerie.
I said largely Gendarmerie, not entirely so. I don't doubt that the French had combat forces, but as your own example shows they were small, poorly equipped, and a number had been sent overseas to fight in colonial conflicts. Not for nothing did the French Foreign Minister confide to the American ambassador on June 2nd "We are defenseless, you know."
