about the power of the GMG... even if i fully agree with starbutt that the GMG won the sig-13 battle by using the terrain rather than a blunt hammer ( flying a huge fleet into the gasclouds just to be ripped to pieces ) - i d still say that the GMG -- today -- must have enough power to stand their own against rheinland opposition.
rheinland has not reclaimed what GMG won ( whatever it was ) in the war. and so i don t think that GMG has to play the victims role when compared to the rheinland military. it happens that RM ( representative for the r heinland fleet ) is one of the stronger factions around - having a GMG faction that can only duck and hide form RM would be a bit strange.
furthermore, GMG is a successful cooperation that delivers their product to many customers - so i d expect them to be a lot less limited to small crafts - and can prolly go for a larger fleet of gunboats ( cruisers and greater rather not ) - but i would expect GMG to have enough equipment to counter an uprising rheinland, cause they might fear a rheinland that is too strong to go for a very late retrubution.
