A tank is a heavily armored vehicle used by the military and in war. In a dream, a tank could represent a very strong ministry.
Positive: Dreaming of a tank could represent that God has given you a powerful ministry or has equipped you with tools for victory.
Negative: Dreaming of a tank that is destroyed could symbolize that your ministry is facing destruction. Dreaming of a tank with broken wheels could mean that your ministry is stagnant and not progressing.
(Proverbs 24:5; Proverbs 14:26; Psalm 88:11).
