Situation report [obj-を]. / Currently targets [topic-は] visual-sighting 4. Maximum 7 [question-か]. Small-caliber firearms [obj-を] possess.
Military/tactical dialogue, very compressed. 状況報告 ('situation report') is compact military Sino-Japanese. The first speaker requests this with just the noun phrase + を (elided verb). 目視 ('visual sighting/confirmation') is military/technical. 小口径火器 ('small-caliber firearms') is a compound. The entire response is a telegram-style series of incomplete sentences — typical of radio communication in fiction. Each fragment stands alone without predicates.
