According to BBC news(Arab League agrees to create joint military force - BBC News the joint arab military force will be consisted of about 40,000 elite members, including land, naval and air force. So considering the number of 40,000 and the word "elite", the best comparison could be:
Netherlands with 37,400 active military
Finland with 37,500 active military
with a less comparable military force as backups:
Oman with 42,600 active military.
For Netherlands, the ratio of the land: navy: air force is about: 2.5: 1.3: 1, with the following equipment:
MBT: 18(Leopard 2)
IFV: ~100(CV9035NL)
APC: ~600
SPH: 57(PzH2000)
SR-SAM: > 36
MR-SAM: 3
LR-SAM: 3
Destroyer: 4(De Zeven Provinciën-class)
Frigate: 2(Karel Doorman-class frigate)
OPV:4(Holland class)
LPD: 2(Rotterdam-class)
Submarine: 4(Valrus class)
Fighter: 87
Transporter: > 4
Attack helicopter: 28
Utility helicopter: 48
For Finland, the ratio of the land: navy: air force is about: 9: 2 :1, with the following equipment:
MBT: 128(Leopard 2)
IFV: 192
APC: 860
Towed howitzer: 471
SPG: 72
MLRS: 34
SR-SAM: 322
MR-SAM: 24
Patrol boat: 8
Fighter: 55
Transporter: 5
Attack helicopter: 28
Utility helicopter: 48
From this data we can see that, the Holland army is heavily emphasizing naval force, while th Finnish army is more focused on land force. So if we normalize the number based on Finnish army(totally 12 points), the ratio become:
Holland: 6.25: 3.25: 2.5
Finland: 9: 2: 1
Holland air force is balanced with enough fighter, transporter and helicopter, so I fix the number for air force of joint Arab military as 2.5, but reduce navy force number to 2.75, then the number of army is 6.75, with the number:
army: 22, 500
navy: 9, 166
air force: 8,334
With the following equipment:
Army(based on Finland number):
MBT: ~96
IFV: ~ 144
APC: ~ 645
Truck howitzer : ~353(don't think they will order towed howitzer for this new army)
SPG: 54
MLRS: 26
SR-SAM: 240
MR-SAM: 18
LR-SAM: 3(which Finland army lacks)
Navy(Based on Netherlands but with more focused on landing force but not air-defence and underwater force, 1 destroyer = 2 frigate = 2 submarine = 2 LPD = 4 OPV)
Destroyer: 1
Frigate: 4
OPV: 6~7
LPD: 4
Submarine: 2
Air force(copy from Netherlands number)
Fighter: 87
Transporter: > 4
Attack helicopter: 28
Utility helicopter: 48
#Note 1: Destroyer and Frigate is discriminated based on whether it is fitted with LR-SAM of SR-SAM
#Note 2: This estimation is based on the prerequisite that joint Arab military force can be an independent force and supporting from the navy and air force from Arabia League is not necessary
