Great !

At the moment, Venezuela is the most obvious and appropriate choice for a new OpFor !!
I made a design plan too for this faction long time ago. =>
here Looks like we roughly has the same basic idea about kit layouts.
-AK-103 as standard rifle (I chose the PSO optic because the Army bought a lot of them with the last SVD order, but current Russian 1P29 is nice too)
-FAL as a secondary rifle (I also think it would be nice to see this old gun in action)
I recommend you to drop the G3 (haven't seen one Venezuela Army picture with it), the P90 and Glock 17 as well (I prefer the Browning anyway ^^).
I didn't found any info about FV106 use, but they got some EE-11 Urutu, both .50 turret and 20mm variant (for "Marines" I think) but they might have been withdrawn from service cause of the arrival of newly bought BMP-3, which could replace altogether all Venezuela outdated APC, IFV and MBT (the French AMX-30 has cardboard box armor). I read something about a modernized T-72 order, but there's so little info it might be a fake.
I say stick to the BMP-3 as the main armored vehicle and discard the rest for now.
For your "Land Transport" category, throw away everything : Venezuela produce its own jeep and has begun to use it :
Tiuna :



It can be used as an anti-aircraft vehicle as well (two Mistrals AA)
For air assets : they use new Mi-17, Mi-35M (no model in PR atm, so we might use the Mi-28 Havok, Venezuela bought ten last year). Still, the Mi-35M would be awesome. The Army also use the Huey.
