In my current game as Germany I have the same problems.In the begining my slovak allies send me 4-5 divisions as help against the poles.But they did nothing at all.After the conquest I put them in Poland as police.And when the partisans came even with 3 infantry divisions in plains they weren't able to defeat the partisans.Only when I send two bombers they won.In the war aginst SU I had 10 armies on the border the slovak divisions and after I declared war Bulgaria send me 3 divisions.One month later they send me another 3 divisions.But hungarians, romanians and italians didn't send me even one division.The italians were in bad situation so I understand them but hungarians and romanians had their divisions in their capital or on the border with Yugoslavia.The yugoslavians went with a coup so they left my alliance in march.But I can't decalre war even now(february 1942).Is this a bug?In reality slovaks, hungarians, romaninas and italians sent armies on the east front, but bulgarians didn't.It is very unrealistic that Bulgaria sends divisions on the front.It would be more realistic that I gain manpower(2 or 3) from Bulgaria as volunteers to SS.But this surely in 1943 or 1944.I didn't get to that year but if this event do not exsist it will be better to have it included in the latest version of TRP.And the sendin of expeditionary forces from Hungary, Romania and Italy but not from Bulgaria as they are used to surpress partisans.Tzar Boris wouldn't send soldiers to the east front because Bulgaria didn't declare war on SU(but still got bombed from their bombers).And instead of building tactical bombers it should be better to build CAS.After all when Bulgaria declared war on Germany all of their army(which was in the Balcans) went against german troops.And against the german troops our army used german interceptors and stukas.And maybe it will be good to have more IC because Bulgaria was in progress in the late 30's, second after Germany in the whole world.
