Nice effort, but I have one very serious remark about quantities of major combat systems of the land forces (page 1).
You wrote that Venezuelan army has 2124 MBT's, 3716 IFV's and a tiny number of just 240 towed artillery pieces, 150 SP artillery and 370 MRL's.
I'm sorry to say, but that numbers imply an organizational structure that is horribly underequipped with artillery, while on the other hand the ratio of MRL's to conventional artillery is unheard of in any other army (in all sizeable armies MRL's are much less numerous than "typical" barrel artillery).
To put this into perspective:
-late 1980s US heavy (armored or mech.infantry) division had 6 or 5 (respectively) tank battalions with total of 348/290 MBT's, and either 4 artillery batallions (3 x 24 M109 and 1 x 12 M110) or 3 batallions (3 x 24 M109) and 1 battery (1 x 9 MLRS);
-late 1980s Soviet heavy (tank or motor rifle) division had 10 or 6-7 (respectively) tank battalions with 322/214-254 MBT's and 7 artillery (4 x 18 D-30 or 2S1 and 3 x 18 D-20 or 2S3) plus 1 MRL batallion (18 x BM-21).
So for a mechanized division it gives ratio of 290 tanks to 72 guns and 9 MRL's (USA) or 214 tanks to 126 guns and 18 MRL's (USSR).
And on top of it there was also artillery belonging to higher levels (corps' and armies in USA, armies and fronts in USSR) - and there was a lots of it.
In US Army there was a varied number of artillery brigades of various strength.
In Soviet army each combined arms army (4-5 motor rifle divisions or 1 tank and 4 motor rifle divisions) had a brigade of artillery with 72 to 90 152mm howitzers and MRL regiment (54 launchers) and on the front level there were artillery divisions (with several brigades of guns, howitzers and MRL's) as well as separate brigades. (and anti-tank artillery, but let's leave that).
EDIT:
P.S. And generally having all that stuff (2000 tanks, 8 aircraft carriers, 3000 aircraft etc.) at just 320 thousand of personnel suggest rather VERY big reserve component - either professional or conscript-based.
(Or rather care-free approach to issue of manpower needs of such large number of equipment)
