Slice by Index with increment

问题

I have something like this:

<div ng-repeat="atma in abc">
   <li ng-repeat="atma in abc.slice(0,3)"><span>{{$index+1}} - {{atma.weapon}} </span></li>
</div>

I wanted to slice these results at, each div repeat, each time being used the 3 items from index.

So I would start with the first div showing the weapons ranging from 1 to 3. The second one would have elements from 4 to 6. And so on.

Can I use $index or something like that on my slice?

Ps.: This question came from trying my best on this question here. I'm still having some trouble, but I made another question based on what I could do with slice.

1st:

<div ng-repeat="atma in data">
   <ul ng-if="$index % 3 == 0">
       <li><span>{{data[$index]}} </span>
       </li>
       <li ng-if="$index+ 1 < data.length"><span>{{data[$index+1]}} </span>
       </li>
       <li ng-if="$index+ 2 < data.length"><span>{{data[$index+2]}} </span>
       </li>
   </ul>
</div>

2nd:

<div ng-repeat="atma in data">
   <ul ng-if="$index % 3 == 0" ng-init="tmp = data.slice($index, $index + 3)">
       <li ng-repeat="atma1 in tmp"><span>{{atma1}}</span>
       </li>
   </ul>
</div>
