Could you help me?

1. Could you check whether the underlined words, 'deadly' and ' formally' are adjective and adverb respectively in the following sentence?

Sifting through the estimates of three non-governmental organizations, the Council on Foreign Relations scholar Micah Zenko published on Tuesday a tally of drone strikes in Pakistan, Yemen and Somalia, the central theaters of deadly and formally undeclared counterterrorism operations run in official secrecy, the Guardian reported.

2. Can the 'assets' be singular in the following sentence? Or, is the 'has' wrong and so it must be changed to 'have?'

There has never been more available, both dedicated US and leased, satellite bandwidth; never been more strike drones available; and there’s more people who can watch full-motion video [for targeting]. There has never been more assets available to kill people and strikes are going down. There’s been a policy decision, and I think they’ve been correct to emphasize that.
