Mobile artillery trucks and scud launchers make their way to the Aribissian trenches. Helicopters offload supplies at the trenches and camo nets are set up to make it difficult for satellites, planes, etc for anything to be pinpointed. Machine guns, sand bags, rebar, etc are included in supply drops. Machine gun nests are set up and barbed wire is strung across certain areas of the trenches. CEVs are also thrown into the mix.
EDIT: Oh hey wait, looks like you attacked me when I didn't even attack.
That's bad news for you bud.
13 lead dust scud missiles are lauched at NA borders, while artillery fires at SAM sites and high concentrations of troops. Infantry advance in APCs/IFVs and MBTs. They stop as they reach the minefields. Tanks cover CEVs as they dig up mines.
