For pilots who are into air-to-ground missions, I've created the following kneeboard cards.
I've focused on types of units that are most common on our 132nd Virtual Wing's trainings and combat missions.
I specifically avoided SAMs/AAAs etc as those air-threats are already addressed by other content makers (Well, I ran across a few while googling )
The intent here is to assist in ID'ing what the pilot is seeing so as to be able to tell a friend fr om a foe, and to have a clear idea about the type of ground force he (or the JTAC he's supporting) is up against.
I hope it would be of assistance.
The cards are maintained on the link below (wh ere additional cards might be added later on):
