Yung commisions na nabanggit common practice iyan talaga world wide...
ang mga manufacturer ng vehicles / equipments, military or civilian nag bibigay sila ng commisions, reward iyun dahil napili mo yung product nila.
specially when you talk about milllions of dollars.
to keep it simple in most countries SOP ang Bidding you have at least 3 manufacturers na mag offer ng product nila sa ganitong price, mag kakatalo iyan sa package offered.
sa performance, technical support, accessories na kasama and requirements ng isang buyer..
yung ibang manufacturer kasi sa price ng unit duon din nila kukuhanin yung pang commision na ibibigay nila, kaya price tumataas.
pero kung ma control ng government natin instead of receiving cash commisions we can ask nalang for better upgrades, improve electronics, weapons, spare engines or parts.
in that way whole country ang makikinabang and not just a few.
