Jakarta – The armed forces will improve discipline among soldiers to prevent incidents of subordinates openly criticizing their superiors, Indonesian Military (TNI) Commander Gen. Djoko Santoso has said.

Djoko, who is retiring soon, said the TNI command would take steps to ensure no more soldiers violated the military code of conduct, which was recently breached by an Air Force senior pilot.

"We will certainly make improvements. In the future, no disciplinary violations will happen again," he said as quoted by Antara news agency on Friday.

President Susilo Bambang Yudhoyono had previously entrusted the TNI and the Air Force to take action against Col. Adjie Suradji, whose article that appeared in Kompas daily on Monday was deemed an open criticism of the President, who is the supreme commander of the TNI.

In a press conference on Wednesday, Yudhoyono called the pilot's act a challenge of civilian supremacy.
