I called it equivalent to MEU to draw parallel to smallest independent functional units in USMC while calling it equivalent to BCT in terms of its engagement capacity, though it matches neither.Not sure if i'd call a MEU a brigade equivalent to an army brigade.
It's basically a batallion of marines (little under 1000 troops) augumented by several tanks, plus some other recon vehicles and an artillery battery. And it has own organic helicopter support - several attack choppers and some transport helos.
Roughly speaking, it has 2-3 times less men and firepower than an US brigade. Though it does have added aviation element.
An USMC MEU is based on 1 btn of troops, PLAMC brigade on 2 btn and a BCT on 3 btn.
PLAMC brigade is equivalent to
2/3 of Stryker BCT + 1x ArmourReg
+ 1x Combat Av Brg ( attached)
So it is more like a Regimental Combat team than an MEU.
