The coastwatchers on Guadalcanal were usually able to radio advance warning to the Australian troops on Tulagi of the approaching Japanese aircraft, but the troops did not have large enough weaponry—three Vickers machine guns and one Bren light machine gun—to seriously challenge the Japanese bombers.
Intelijen penjaga pantai di Guadalkanal biasanya dapat mengirimkan pesan radio peringatan dini kepada pasukan Australia Tulagi ketika ada pesawat Jepang yang mendekat, tetapi pasukan Australia di Tulagi tidak memiliki persenjataan yang cukup (tiga senapan mesin Vickers dan satu senapan mesin ringan Bren) untuk menghadapi tantangan serius dari pesawat pengebom Jepang.
