"Big Mek Zagwizza leads the approaching Ork force. These Orks are members of Warboss Tufgob’s Waaagh! and are equipped with gear that they brought with them to the planet or looted from Imperial forces. His forces include the following:

• Five Lootaz (see page 239) led by a Nob (see page 239).
• Five Burna Boyz (see page 239) led by a Nob (see
• page 239).
• A Looted Hellhound Flame Tank (see page 157).
• One Wierdboy (see page 242).
• Ten Gretchin"

(Pg. 259)

Then suddenly on Pg. 260…

"Unless there are compelling strategic reasons to use a different strategy, the War Trakks begin the assault by attempting to blast a hole through the outer wall"

Err, where did the War Trakks come from? and how many are there? This is never covered other than the fact that they are described in plural, so more than one. Also there are no armaments given other than a mention of their "salvo"

what the hell is an ork trakk anyway? I thought they were Trukks?

A wartrakk is a warbuggy with tracks instead of wheels. (I had a 1500 pt ork army in 4th edition.)

Ya, that definitely seems like a mistake: I assume some number of Wartrakks are supposed to be included in the listing of his forces on pg 259 C2. Good catch, I don't know why that didn't stick out to me on the read through.
