The People's Army committed their armour into battle in battalions,
Tiểu Đoàn Thiết Giáp (pronounced thee-ow doh‑ahn tee-et harp), and grouped these into entire regiments.

As aid from China and the Soviet Union increased, their armoured strength grew rapidly from a single battalion in 1965 to three armoured regiments in 1971. This gave them a significant advantage over the puppet forces as each battalion had more tanks than an entire ARVN armoured brigade.
