Why can the division sent to Malaya in 1939 be termed 'forward defence'?

The division sent to Malaya in 1939 can be termed 'forward defence' because it was intended to establish a military presence in the region to deter potential aggression from Japan and to protect British colonial interests in Southeast Asia. By positioning troops in Malaya, the British aimed to create a buffer against invasion and maintain control over vital trade routes. This proactive strategy was designed to project strength and discourage adversaries before any conflict could escalate. However, the effectiveness of this approach was ultimately challenged by the rapid Japanese military advances in 1941.
