D85. WP inf riding APC's question

[Mafooo]

Hi,

Most of my WP infantry can turn in to T mod and ride APC's. However, per the rules since they are in T mode they have half defense against a hard attack.

I thought that the purpose of APC's was to provide protection for infantry on the battlefield, yet it seems they are more vulnerable otherwise. Can someone explain? Thanks.

(Note I know this provides them protection from units with soft attack values, but in the Bolt out of the Blue scenario, it seems that most of the quality NATO infantry have both high soft and high hard attack values, which negates the APC value. Thanks.)
