Yes that's one possible (and most likely use) however, I knew he had no or extremely little armor research done and after all these years I'm sure any points he may have had for research/production are long drained away, so they'd be pretty expensive to gear up for. However anything he's done with is infantry would cross over to the para's, though not having them researched (triggered) is a problem, between research and training them, it would take him a year and that's not useful for now. :/ I hope his lack of development and flexibility for his ground forces isn't coming to haunt him now, time will tell. Though it sounds like any new troops of what he can train is several months away. :/

In this case, inflexibility would be the more appropriate word. I am sure he could shift some research into arty and armor, he also ought to be able to license some. The longer he waits, the worse it will get. He needs to beef up his land force with more than infantry. He should start now, eventually he'll get some benefit from it. Same with air techs. He will end up with this wonderful fleet, but with nothing useful for it to do other than support pin pricks against the big boys, because his army can't stand toe to toe against them.
