I was in the early 70s, the last of the Vietnam debacle, we had a M2 and 3, Nikon F, non metered head, 35mm, 50, and 200mm lens, Superspeed Graphics which we did not use in the field, too large and heavy to be lugging around, a Graphic XL which we did nor take into the field as it was unreliable. Some units had Rollie, cords and flexs, I've talked with some at stateside bases who said they had Yashica 124 and Ds, I never saw one. Until the late 70s a lot of state side bases were still using a variety of Graphics, 4X5 and 2X3, also Bessler's 4X5 which was an improved Busch with cams for a set of lens. The Navy was shooting Topcon and Canon F1. The last base I was a photographer was Mather, we used Graphics XL later Konica Rapid. The superintendent was a civilian, he felt that 35mm was miniature camera only good to shoot slides for technical purposes and kept the Nikons locked up. We also had a 4X5 view, don't remember which made and a Burk James 5X7 Rembrandt studio camera with 4X5 reduced back for portitrates. I once saw the table of allowance for out unit, we had a lot of old gear that should have been sent to salvage but was kept on hand and hidden when the I.G came snooping around.
