On a class of groups with strongly embedded subgroup

It is proved that a group $G$ with finite involution and strongly embedded subgroup of shape $B=R\times T$ where $R$ is an abelian periodic subgroup, $T=U\leftthreetimes H$ is a Frobenius group with abelian core $U$ containing involution is isomorphic to $R\times L_2(P)$ where $P$ is a locally finite field of characteristic $2$.
