It is important to know with manga that the authors sometimes choose to use an unusual or non-standard gloss (furigana) next a set of kanji. Sometimes, as in this case, the gloss comes from English.
Part of what might be giving you trouble in this case is that (a) there are no word breaks shown; and (b) all furigana characters are the same size, even if some would normally be the small versions in full-size text.
Below, I have altered the text in light of these issues to help you to decipher it.
フォース・コンバット
タッグ・マッチ
Finally, note that the 本 kanji is glossed as ぼん in this case because it is being used as a counter word, following "3".
