From XTRO Primitives Vol V, p. 6, "ARC-1A Archer, Overview", mid-4th paragraph:
"Praised for its reliability and ease of maintenance, the ARC-1A remained the Hegemony standard for more than a decade and a half before technological progress enabled Earthwerks to produce the more efficient ARC-2R model, which debuted in 2475."
MUL, TRO 3039, p. 296, and TRO 3025 (original, FASA), p. 92 says 2474.
p. 8, "BWP-X1 Ymir, Overview", mid-2nd paragraph:
"While its armament drew on the Mackie’s arsenal as a template, pairing a class-5 autocannon with a large laser in opposite arms, the greater amount of overall tonnage available for weapons enabled the Ymir’s designers mounted a veritable hodge-podge of weapons to cover a wide range of battlefield conditions."
Grammar, suggested change: "to mount"
