here are a few suggestions regarding the Belgian equipment and units.
Thanks for that DLC, it's quite uncommon to have the opportunity to enjoy them in a wargame.

Aircraft
- ID 168: The Alpha Jet's height is 4.2, rather than 2.5 (same for the French Alpha Jet, ID 150, and the German one, ID15)
- ID 169: The F-84F carried 127mm HVAR Rocket (377), instead of the FFAR rockets. It could also drop Napalm
- ID 171: Mirage 5BA was operational in CAS role from the 5th of March 1972. It could drop 2 iron bombs, or 2 cluster bombs, or napalm, plus 2 rocket pods or 2 Sidewinders
- The 06 of May 1980, the 349 Sqn. became the first NATO squadron ops on the F-16A on the 7th of January 1981. Block 5 and 10, probably the same as the Dutch.
