how many windbusche jaeger units!!

hi all,

the other day i had a 2 v2 battle, i was france and my directly opposite opponent was austria, i got mauled mainly due to me losing all my art in the first five mins because it would nt fire in time to stop the one light cav that came and knocked them all out, anyway i was hosting so after i was routed i noticed that my opponent had 4 x windbusche jaegers!!!
now ive checked since and was pretty sure anyway that you can only have 2 per army, i kept questioning him on the ingame chat as to how he could have 4 x teh unit and he eventually replied and simply said 'magic'!!

how is this possible, could he have altered game files or something to allow him 4? either way surely this is cheating and was wondering how it could have happened as i was under the impression that multiplayer was pretty free from being able to cheat?

any ideas, opinions?

cheers
