Thailand need to start rethinking all of it's military needs! Today it's a big operation with to many players, as you say "High quantity but low quality" for comparison Thailand had 1,750 flag officers compared to about 1,000 flag officers in the US armed forces 2013!

And much of the equipment that they have is old, outdated or just poor quality due to corruption.

What they need to do to reform them self:

Specialization of units. Highly trained/specialized units like SAS, USMC and Spetsnaz are what's needed for the future of infantry but most of the Thai army is low educated/trained riflemen.

Specialist training. I had the opportunity to join my students in the Army Reserve one time and I realized that: 1. It's not much real training. 2. I'm a better marksman and know the HK33 better than their instructor!

A mayor overhaul of the equipment. Small arms in use today: 3 different pistols, 4 different SMG, 11 different assault rifles and 8 different machine guns. 11 different howitzers and so on

And last but not least a BIG reduction of flag officers.

"And last but not least a BIG reduction of flag officers."

Like that's ever gonna' happen. You might as well ask for, oh, say, the elimination of corruption...

They obviously feel the need to update that video of the military in action which they show when the National Anthem is on the telly!
