I submit that if one were to rank real Life battles-in "non" CM nomenclature- in terms of probability of occurence they would be:
1-Assaults (By far the most common)
2-Attacks
3-Probes
99- Meeting Engagements
1,000,000-Out of shape guys in their underwear, sitting in front of a computer screen eating potato chips, thinking they are anywhere close to experiencing "real" combat
