Habka wax-soo-saarka tuubooyinka birta ee aan kala go'a lahayn. Marka loo eego habka wax-soo-saarkeeda, tuubooyinka birta ee aan fiicneyn waxay u kala qaybsan yihiin tuubooyinka birta ah ee kulul, tuubooyinka birta ah ee qabow-jiidka ah, tuubooyinka birta ah ee feedhka iyo fidsan, iyo tuubooyinka birta ah ee aan tooska ahayn. Labada hab ee ugu horreeya waxaa loo isticmaalaa in lagu soo saaro tuubooyinka birta ee guud ahaan-caliber-ka, dhexroorkoodu guud ahaan waa 8-406, dhumucdiisuna guud ahaan waa 2-25; Labada hab ee dambe waxa loo isticmaalaa in lagu soo saaro tuubooyinka birta ah ee dhumuc weyn leh, dhexroorkoodu guud ahaan waa 406-1800, dhumucdiisuna waa 20mm-220mm. Marka loo eego isticmaalkeeda, waxaa loo qaybin karaatuubooyinka birta ah ee aan kala go 'lahayn ee dhismayaasha, tuubooyinka birta ah ee dareeraha ah, tuubooyinka birta ah ee aan kala go 'lahayn ee kululeeyahaiyoDhuumaha birta ah ee aan xuduud lahayn ee dhuumaha saliidda.
