Good thing about F5 is that it has some capability to use unpaved runways. Notice the engines are at the sideways far above the ground so Fod blocker engine doors like Mig 29 are not necessary on inlets. An example below shows grass runway landing and take off. Some landing gear modification is necessary too to use these types of runways but main thing is the fod blocker or fod avoidance of jet inlets.
Mig 29 uses a different option with fod blocker door on engine inlets. That is why Ukraine used them on improvised airfields for a very long time after their airbases are bombed by Russia at the beginning of the war.
Both fod blocker doors or upper inlet positions like sideways(F5) or top(stealth drones Valkyrie etc.) are necessary to use unpaved runways which is crucial when facing an enemy having higher stand off weapons advantage. Temporary improvised runways can be built and used continiously increasing the survivability of the aircraft.
Any ability to take off or land using improvised grass runways is an excellent ability.
