Starting weapons with loadouts

Am I correct in remembering somewhere someone or other at some point in time said that primary weapon choice for Loadouts will be limited to BR, AR, AC (Assault Carbine, whatever that is), DMR and Covenant Carbine? If so, I don’t have an enormous problem; those weapons are decent all-rounders (to our knowledge) and none has an enormous advantage over any others, except for the AR not being great at medium-long range. In which case, pick a scoped weapon on the appropriate maps, -Yoinks!-.

Secondary weapon will be Plasma Pistol or Magnum, correct? Slightly bigger problem is the PP’s EMP function…
