Recce equipped aircraft are totally irrelevant to the SP series. Fixed wing air is attack air.
The spotter plane is there for slow prop-driven Austers early on, or UAV later on. Recce helos are normal light helos.
Early on, some OOB designers did go potty, and make "spotter planes" with helicopter icons, or even fixed wing jets. Those were removed from the offending OOBS since the spotter plane flies at prop speeds, makes a prop sound, and flies a tight circle no jet could manage
. The helo versions were redundant as mentioned above - the light helicopter class already does this.
Fixed wing recce is irrelevant as any line scan recce pod data would need to be sent to an intelligence cell first, and interpreted before being sent on to high level HQ. So the data would not arrrive at the battalion level in any timely enough manner for a 1 hour or so game even if flown in turn 1.
Recce fixed wing planes might be valid items if this was an operational level game with batallion sized counters and half-hour turns modelling a day or 2's combat in a game, but not at this level.
