Which ever chopper that can carry best anti-tank weapon(Hellfire). What other missile lets you choose flight parameters and weight only 100 pounds? There is a tank in the open? I'll choose high profile to hit top of armor. Tank hiding under a tree? I'll choose direct profile. Hiding under overhead with only little bit showing? Low profile - I choose you. Vehicle driving with high speed and weaving all over place? Yep - Hellfire can assist easily.
