Of the export variants, 
Moroccan F1's saw the most heavy combat usage after the Iraqi F1's.  
With Libya next in line, most probably. 
Only 4 export variants are "real" 2nd Generation F1's (original, non-updated) with digital Nav/Attack System : 
F1EH 
F1EDA 
F1EJ 
F1EQ (inclusive the EQ4, 5 and 6)   
All others are generally F1C with an inertial navigation system. Their cockpits 
generally have a similar configuration like a F1C, the main difference is the INS panel on the right-hand console. 
Dassault regarded all F1's with INS as Multi-Role.   
Short nose / long nose  
Early F1C without IFR capability have the "short nose" , i.e. the "normal" fuselage length. 
The F1C-200 and all other variants with IFR capability have the forward end of the fuselage re-constructed and  
lengthened by 8 cm. There was no "plug", as it is so often mentioned in literature. 
There are three variants without IFR capability but which have the lengthened fuselage : 
F1CK-2 
F1EDA  
F1JA
