[DRG]

Normally I recommend using Trucks for "fake" landed aircraft. I don't see the point in using bunkers but in this case, the ones I checked had the amour reduced to zero.

The wide variety of ways to handle an issue is what keeps this game "interesting" and yes, the size of the unit can be easily changed in-game using the Edit Unit Data screen. NORMALLY you would not want bunkers spotted from a distance unless it was a fortress. A G4M in the game is size 5 and an A6M would be 3 but it's a minor detail as they are "non-combatant"

What I find interesting is this editing feature seems to be unknown to even experienced players
