The 1/35 Merkava Mk IV kit from Academy builds very nice. Academy also includes PE in the box to add extra detail.
The detail of the sprues is very nice and the built is pretty easy.
Nowadays there are multiple PE and aftermarket sets available for this great kit, so you can add even more detail to it!
Academy has created an easy to built kit with this one, I found no issues with the build and the detail is pretty good! Only downside I noted are the tracks, they come in long straight pieces and are not workable at all, without natural sag of the tracks they look pretty weird.
On the other hand, the PE included by Academy is nice! you will create the ball and chain turret armour with it and and some other details impossible to create with plastic.
