Accustomed to deploying in my own field?

Does "accustomed to deploying in my own field" mean "accustomed to distributing systematically or strategically in my own field"?

Context:

For better or worse, I attended two days at the Cambridge con-
ference, giving a talk of my own and taking part in the discussion
of several other talks. I challenged the theologians to answer the
point that a God capable of designing a universe, or anything else,
would have to be complex and statistically improbable. The
strongest response I heard was that I was brutally foisting a
scientific epistemology upon an unwilling theology, f Theologians
had always defined God as simple. Who was I, a scientist, to dictate
to theologians that their God had to be complex? Scientific
arguments, such as those I was accustomed to deploying in my own
field, were inappropriate since theologians had always maintained
that God lay outside science.
