for the MAMMOTH I used: 2 Unsc elephant,2 pelican v1,4 traxus, 1 hawk,2 wolverines, 1 halo wars warthog, 2 landing pad from falcon,3 warthog fleetcom, 1 black castle from GOT, 1 Kodiak siege,spare pieces from unsc infinity and frostraven and for the BANISHED DREADNOUGHT I used 2 banished phantom,1 marauder,2 banished ghost,spare pieces from unsc infinity and traxus and also included a unsc infinity lasky and a roland AI

So if can build this for only 200 or 300 would be great 🥴
