TM, p. 351 lists both AA weapons as "(B)A", indicating they are ballistic weapons.
AToW, p. 274 lists both weapons in the Missile Launcher table.
The very heavy weight of the ammunition in the TM table supports that they are in fact missile launchers and should thus be labelled "(M)A". But I thought I'd ask here first before posting errata.
Xotl: handled in the latest TM errata.
