It also lets you have some extreme fun with some reward units (cloaking sturmpanzer and cloaking Flakpanzers come to mind), altough thats auxillary.
IIRC It also gives the 15m medic bunker heal aura, not entirely insignificant.
(The T3 before it is good to)
Also, there is some officer changes pending next patch.
Unfortunately it does not work on flakpanzers (Guess who tried it?
) So it was lack of data it provides (didnt know its squadleader based), I think medbunker only gets it in fatherland defence and not in Middle T4?
