For the most part, the HMG is the mainstay that will be used in firefights. And with a BS 15 and mimetism, the Tikbalang is going to win most of its firefights it will engage in. While the Heavy Flamethrower is used more for point defense on the Tikbalang, it can be certainly be used to have a template weapon to deal with camo and ODD units. As well, Climbing Plus is going to allow the Tikbalang to reach unexpected angles to attack from.
Being that the Tikbalang sits at a below average WIP 12 and only slightly average BTS, it can be vulnerable to hacking attacks. Hence you will need to keep it far away from opposing AHDs and their repeaters.
