working / meanings of the loXX files..

Lo XXTTSS.dat files
XX=class object type : city files, landmark files etc.
TT=class location type 
SS=serial number

lo01TTSS  : front positions Single Play :
they are containing pointers that are pointing at lo13xxxx files, combining them to front positions.
these are ONLY used in brigadeX.dat files, which ONLY work in Single Play. They are the source of the active soldiers in RBII, 
but not available in RB3D.

lo02TTSS : location files for Single/MMP play such as aerodromes etc. they contain objects hangars, trenches, cars, shacks, factory buildings etc 
lo02TTxx 
TT = type of location : 
    00 aerodromes
    01 multiple meanings:
       cities : containing buildings.
       frontpositions: in the brigade#.dat files they point at lo13xxxx files, describing frontpositions
       also used in custom mod RFS, real front server.. 
       which contain mg nests, tanks, soldiers, balloons, etc for MMP frontline. 
       these would also work in SP. (custom mod)
    02 supply sites : warehouses, shacks, with MG nests and trenches.
    03 rail yards containing station, trains, wagons, etc.
    04 complete bridges. they combine bridge parts to a single bridge + some MG nests / Flaks.
    05 factory sites. factory buildings, trucks, shacks, MG nests, etc etc
    06 companys (units of soldiers) for Single Play. Not in default game files. Erratic in the game: sometimes show, sometimes they do not. if a 06     
       is allied, it cannot have german MG nests, for example.. They do show on kneeboard map: show like brigades. I decided not to use them. feel free to experiment.
    07 towns. they point at lo14xxxx tiles, that contain the buildings..
    08 villages. they point at lo14xxxx tiles, that contain the buildings...
    

lo13TTSS  : front files for brigades in Single Play  : 1300 - 1303   00 and 01 = allied, 02 and 03 is german.

lo14TTSS  : city tiles  : 1410 - 1418 (hex numbers ! )  city tiles, these 9 are used to build every city / town / village in RB mmp and sp
