[ARC5] Basic Question on Use of Command Sets

[Bob Macklin]

During the Korean War we used T-6s for Forward Air control. Our T-6s had 
ARC-5 VHF radios only. No HF liaison equipment.

The WWII Observation aircraft like the L-1, L-2, L-3, L-4, and L-5 were also 
not large enough to carry a liaison set.

The navy scout bombers (SBD, SB2U, SB2C) also carried both command sets as 
well as liaison sets.
